The Internet of Things (IoT) is a technology whose goal is to integrate devices into the Internet. Many previous studies have been carried out as an example on blood volume, blood pressure, and pulse monitoring devices which aim to select blood donors based on blood pressure and blood volume with external storage. The existence of an analog manometer measuring device is part of a conventional needle panel pressure measurement which could have an error in measuring the pressure. The need to use a digital manometer to properly prove gas pressure. This digital manometer can provide more accurate and detailed gas pressure information through the LCD display. Liquified Petroleum Gas MPX5700 LCD Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 Figure 12 Figure 13 Figure 14 Figure 15 Figure 16 Figure 17 Introduction Liquefied Petroleum Gas (LPG), which was introduced by the government to replace kerosene, has improved gas combustion and decreased air pollution. However, as evidenced by data from the Depok city government covering a five-year period, the increased flammability of LPG in high-pressure environments can result in catastrophic explosions. LPG was specifically blamed for 17% of gas-related fires (Judge & Jonathan, 2017). According to Setiadi and Muhaemin ( 2018 ), the Internet of Things (IoT) is a technology that attempts to seamlessly connect items with the Internet. The Internet of Things (IoT) is a connecting infrastructure between the real and virtual worlds, achieved via the exploitation of data capture and communication technologies, according to the coordinator and support action for global RFID-related activities and standardization (Mukhopadhyay & Suyadeyara, 2014). Modern system design depends heavily on the IoT, which also makes it easier for information to flow. The notion of IoT in industries and daily life is influenced by integrated computer technology, storage, and system applications (Palatella et al., 2016 ). Blood pressure, pulse, and blood volume monitoring devices that choose blood donors based on these factors have been the subject of earlier investigations. Research on blood pressure and body temperature monitoring devices has shown that such devices have external storing capabilities (Alfian, 2017 ; Aritonang, 2021 ). Regulator manometers, which are frequently analog, are susceptible to measurement mistakes, which causes them to read gas pressures incorrectly. To prevent consumer financial losses, accurate gas pressure information is required. Consumers frequently buy LPG gas cylinders primarily for their weight. Accurate readings of gas pressure are further hampered by the sale of analog manometer-based regulators to customers, which have subpar units and only employ colors and numbers. A digital manometer instrument is needed to depict the real condition of gas pressure via an LCD display with more accuracy and detail in order to address these challenges. Theoretical basis Arduino Uno The unique Arduino microcontroller board has many advantages over other boards of a similar nature. The Arduino claims its proprietary programming language, which is based on the popular C language, in addition to being open-source. Furthermore, the Arduino board differs from most other microcontroller boards in that it includes an integrated loader in the form of a USB interface, making programming easier. Most other microcontroller boards require a separate loader circuit to input the program into the microcontroller. The Arduino board's USB port doubles as a serial communication port in addition to being a loader for programming, increasing its adaptability and usefulness for a variety of applications (Mochtiarsa & Bachtiar, 2014). MPX5700 The Motorola MPX5700 pressure sensor is distinguished by the combination of a signal cooling circuit and a temperature calibrator, which guarantees the sensor's durability against temperature variations. The sensor works based on the piezoresistive principle, which causes material deformation with an effect that is primarily focused on changes in resistance value. According to Mufidah, Setyawan, Gunadi, and Suseno (2018), the sensor has a measuring range of 15kPa-700kPa, or 0-101.5Psi, and its analog output ranges from 0.2 to 4.7 Vdc. Thingspeak Cloud There are numerous options for enhancing Thingspeak's capabilities, such as integrating plugins that let users see Google gauges and other unique data visualizations. The channel entity, which serves as a repository for the aggregation and storage of data supplied from several dissimilar devices, is the core building component of Thingspeak (Nettikadan & MS, 2018). MIT App Inventor According to Axel, Najoan, and Sugiarso (2017), App Inventor is a system created for the development of Android applications that differs from existing development techniques by relying on visual interaction rather than writing lines of computer code. Methods The author admits the need for a monitoring system that can aid humans in effectively monitoring the gas state in real-time based on the situation. The proposed system makes use of an Arduino gadget that is linked to a sensor gadget that includes an MPX5700 sensor that can measure the gas pressure in an LPG cylinder. The measured data is precisely shown on the LCD display and sent to a server created for data storage at the same time. The system architecture seeks to offer a user-friendly interface that makes it possible to monitor residential gas conditions quickly and effectively. The schematic for the framework is shown below. The MPX5700 sensor is used to collect data on pressure from a gas cylinder in the construction of the input system. The Arduino board receives the pressure readings as voltage values, which it then converts into pressure units. The principal information medium is then the LCD screen, where the processed pressure data is shown. The ESP8266 01 module serves as a bridge between this system and the internet in order to enable connectivity to the cloud network. Once connected, the cloud will receive and store the data the Arduino board processes as an online database. The user can then access this cloud data via their smartphone to view pressure data in real-time. To further comprehend the design of the IoT-based LPG gas pressure measurement system, a schematic illustration is provided. MPX5700 Sensor Circuit The sensor in question is able to take readings of gas pressure between 0 and 700 kPa, and then show the information on a liquid crystal display (LCD). With the help of this functionality, the system can identify whether the gas pressure inside the cylinder is above or below the permitted range. LCD circuit The system created to display sensor readings for measuring gas pressure uses a 16x2 LCD as an output device. The user's access to more precise and accurate information produced from the sensor readings is made easier by this display. Open and Locked Regulators The regulator can be locked or unlocked thanks to the regulator valves. The regulator can accept gas from the tube and let it to flow through the tube hose leading to the stove when it is locked. The valve tip is above when the valve is in the open position, as seen in the illustration below. The end position of the valve with regard to the locked regulator is located below. The regulator valve is locked by turning the valve 180 degrees counterclockwise from the open position to the locked position. As seen in the illustration below, this will cause the valve tip to be pointed downward. MPX5700 Sensor Data Collection The sensor is interfaced with the regulator to collect data on the sensor; during the data collection process, the manometer regulator is replaced with the sensor by establishing a link through a hose that facilitates the gas flow. The sensor detects the gas thus passing through the hose and generates the associated pressure reading. To make sure the data is accurate for the real-world situations, the obtained sensor data is then compared with the original manometer reading on the regulator. Data analysis By carefully examining the data gathered by the sensor and contrasting it with the readings of the manometer attached to the regulator, the MPX5700 sensor's analysis is carried out. The experimental process comprises applying gas pressure to the sensor, recording sensor readings, and processing them further using the preconfigured Arduino application. The accuracy of the pressure readings obtained by the sensor is then verified by comparing the manometer data with the relevant sensor dataset. MPX5700 testing During testing, the MPX5700 sensor is used to more precisely measure the gas cylinder's contents. The researchers have noted that it is unknown what is in the gas cylinders used in community dwellings. At the moment, manometers sold with regulators just show numbers and colors, with no explanation of what the colors stand for. It's not clear if the red hue denotes a full gas supply in the tube or if it denotes another color. Users of LPG gas cylinders frequently have this uncertainty about whether the cylinder is fully or partially filled. Even when the contents of the tube do not correspond to the amount specified, such a restriction is frequently disregarded. A newly purchased gas cylinder was once weighed by researchers, who discovered that it weighed about 7.8 kg overall, with the gas inside the cylinder weighing about 2.8 kg and the cylinder itself weighing about 5 kg. However, the researchers did not take into account the actual unit form when they used the manometer regulator to calculate the contents of the cylinder; instead, they only used the colors that were present. According to the LPG specifications published by the Directorate General of Oil & Gas No. 26525.K/10/DJM.T/2009 (Pertamina, 2010), the LPG product must contain at least 97% Propane (C3) & Butane (C4) mixture and at most 2% of Propane (C3) & Butane (C4) mixture, with a maximum pressure parameter determined by steam set at 145 psi. Table 1 MPX5700 Sensor Test Results Volt kpa psi bar 0.2V 4.5V 28.089 kPa 697.861 kPa 4.073 Psi 101.190 Psi 0.3 bars 6.9 bars The goal of the experiment was to evaluate the MPX5700DP sensor's performance when used to gauge the pressure within a 3 kg gas cylinder. The manometer was removed from the regulator by the researcher prior to the test by removing its nozzle and replacing it with a hose that linked directly to the sensor. When measuring the initial gas state with a pressure of 0.3 bar, the sensor was made to display a minimum voltage of 0.2v, which was displayed on the LCD that was programmed with Arduino code. An alarm was added to the sensor to give people a heads-up when gas was running low. The alert was set to go off when the gas pressure dropped below 0.5 bar. Gas customers were given the opportunity to plan for future gas supplies and prevent unexpected stove shutdowns as a result of the buzzer sounding and alert message being displayed on the LCD. The MPX5700DP sensor reads 4.5 volts when the pressure is at 7 bar, which is equivalent to 0.7 MPa, as shown in the illustration, when the regulator valve is rotated to allow pressure to be received by the sensor. The authors of this paper evaluate the effectiveness of current regulators to their newly created gas pressure monitoring system. In order to compare two regulators, one of which is a basic model that just shows numerical values between 0 and 10, without any indication of a measurement unit. The range of the other regulator, which shows pressure in bars (MPa), is 0 to 8. The newly built sensor was able to produce the desired findings (as shown in the picture) when the experiment's fundamental regulator was tested, as shown when the needle manometer pointed to number 7. Regarding the second regulator, it should be noted that the manometer's needle pointed to the number 8, indicating a slight discrepancy from the sensor's results. The researchers next examined the condition of the second regulator in order to assess the level of error in the sensor created for this regulator. Initially, raw data in the form of voltage was taken straight from the gas cylinder and transformed into the pressure units of kPa (kilopascal) and psi (pounds per square inch). The researchers used an equation found in the thesis of an automated water rocket launcher to make this translation easier: Volts = V * (5 / 1023) (1) Since the voltage received did not fall within the anticipated range of 0 to 5 volts, pin A0 of the Arduino microcontroller was used to measure the analog value that the Arduino had been given. The voltage value was then translated into the proper pressure units after being obtained. The thesis on automatic water rocket launchers, which is included in the appended documents, served as the basis for the formula used to calculate pressure values in kilopascals (kPa) and pounds per square inch (psi): kpa = ((Volts /5) – 0.04) / 0.0012858 (2) psi = kpa * 0.145 (3) The pressure range that this sensor is capable of monitoring varies from 15 to 700 kPa, as stated in the MPX5700DP sensor datasheet. It's important to note that 1 kPa equals 0.145 psi, although the barometer reads 1 psi as 6.89 kPa (as noted in the datasheet included). The information acquired from the sensor can then be deduced from the table below: Table 2 MPX5700 sensor testing with Regulator First Regulation (Without Unit) Second Regulator (Unit) MPX5700 sensors Error et Et2 Squared Error 0 0bar 0.3bar 0.3bar -0.3 -0.3 0.09 0.01 7 8bar 6.9bar 6.9bar 0.1 1,1 0.09 1.21 Sum of Squares Error 0.18 1.22 Mean Square Error (MSE) Value 0.09 0.61 The Mean Square Error (MSE) is first calculated in the current study by comparing the obtained and actual values. By deducting the outcome value from the actual value, this error is calculated. According to Gofur and Widianti's (2013) research, the error can be calculated using the formula below. Et = Xt – Ft (4) Information: et = error value Xt = data actual in period t Ft = data results in period t The error values between the actual and outcome values are then squared after being obtained by subtraction. The acquired values are then used to calculate the Mean Square Error (MSE) value. The MSE is a measure used to assess the accuracy of the findings. More precise results are shown by lower MSE values. The MSE value can be calculated using the formula shown below: MSE = ∑ Et2 / n (5) Information: Et2 = squared error value n = lots of data Based on the information in Table 2, it can be concluded that the MPX5700 sensor experiment employing the regulator produced results with a high degree of precision, as evidenced by the Mean Square Error (MSE) number. Testing LCD 16x2 This experiment aims to evaluate the LCD's performance in accordance with the Arduino's programming. In this system, the LCD's main function is to display the information acquired from the MPX5700DP sensor, which is regarded as a critical part. This sensor is anticipated to serve as a digital manometer value, as was previously stated. The display of input data from the MPX5700DP sensor, with the output being presented on the LCD, was used to test the system's LCD's operation. The LCD readout specifically stated "Gas Contains 7.0 bar", proving that the specified functionality was carried out as intended. Android App Testing In this study, a smartphone app was used to keep track of the gas's condition, including leaks and pressure data that were sent to the cloud platform Thingspeak. Researchers had a convenient tool for making smartphone applications when they used the cloud-based MIT App Inventor to construct the application. Conclusion and Advice The study comes to the conclusion that the created system can efficiently and precisely identify LPG gas based on the findings and evaluation. The information about the gas level is efficiently shown on the smartphone's user interface and is uploaded using esp8266 01 modules over an internet connection. Additionally, the system successfully transmits the data to the cloud with a one minute, two second delay. Additionally, the data collected offers helpful information on gas leak levels and precisely gauges LPG gas pressure.

The manometer was removed from the regulator by the researcher prior to the test by removing its nozzle and replacing it with a hose that linked directly to the sensor. When measuring the initial gas state with a pressure of 0.3 bar, the sensor was made to display a minimum voltage of 0.2v, which was displayed on the LCD that was programmed with Arduino code. An alarm was added to the sensor to give people a heads-up when gas was running low. The alert was set to go off when the gas pressure dropped below 0.5 bar.

Initially, raw data in the form of voltage was taken straight from the gas cylinder and transformed into the pressure units of kPa (kilopascal) and psi (pounds per square inch). The researchers used an equation found in the thesis of an automated water rocket launcher to make this translation easier:\u003c/p\u003e\n\u003cp\u003eVolts = V * (5 / 1023)\u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp;\u0026nbsp;\u0026nbsp; \u0026nbsp; \u0026nbsp;\u0026nbsp;(1)\u003c/p\u003e\n\u003cp\u003eSince the voltage received did not fall within the anticipated range of 0 to 5 volts, pin A0 of the Arduino microcontroller was used to measure the analog value that the Arduino had been given.

The Internet of Things (IoT) is a technology whose goal is to integrate devices into the Internet. Many previous studies have been carried out as an example on blood volume, blood pressure, and pulse monitoring devices which aim to select blood donors based on blood pressure and blood volume with external storage. The existence of an analog manometer measuring device is part of a conventional needle panel pressure measurement which could have an error in measuring the pressure.
