Abstract:
Colloquially known as “gas cylinder”, Liquefied Petroleum Gas (LPG) is a source of energy used for cooking and heating. In the era of information technology, humans tend to develop a better and more convenient lifestyle. Wireless technology has already become an important application which usually integrated into a wide range of devices and other technologies. Nowadays, almost all electronic devices are equipped with wireless technology. This fact shows the necessity and benefits provide by this technology. Therefore, I am intended to develop a system which is called Intelligent LPG Gas Level Indicator. People know that Liquefied Petroleum Gas (LPG) is widely used in households. So, the purpose of developing this project is to measure the gas level inside the gas cylinder. The main component for this Intelligent LPG Gas Level Indicator is an Arduino UNO, an HX711 Load Cell Amplifier, and a Load Cell Sensor. This project uses the HX711 Load Cell Amplifier to amplify the low-voltage output of the load cell and sends it to the Arduino UNO so that the Arduino UNO eventually calculates the weight from this data. The Arduino UNO will process the collected data and send it wirelessly to mobile application (Telegram). With the help of a load cell sensor, the mobile application will display the percentage of gas left in the cylinder. The percentage of gas remaining in the cylinder is updated continuously in the mobile application that is being used by the user, and when the gas level is partially full or empty, the user will receive an alert in the application.
