Development of Smart Monitoring and Gas Leakage Detector for LPG Gas

Abstract

The main purpose of developing this project is to detect gas leakage and measure the gas level inside the tank using a load sensor. Then, Blynk mobile application will notify the consumer when the gas tank is out of gas, and the leaked gas is detected. The mobile application will also display the collected data from the sensors. People nowadays are less aware of the LPG Gas tank in their house. The leakage from the LPG tank can lead to fire accidents as the gas inside the tank is a combustible gas. Why was research needed? The main component for Smart Monitoring and Gas Leakage Detector for LPG Gas is ESP8266 NodeMCU, Load Sensor, HX711 Load Cell Amplifier and MQ-9 Gas Sensor. The accuracy and sensitivity of both sensors are measured as the consumer will monitor the collected data. Both sensors are functioning well, even though the accuracy of the sensors is not 100% accurate. This project uses ESP8266 NodeMCU to control the system and as a platform to send the collected data to mobile applications wirelessly. The project has achieved its objectives which is to detect the gas leakage and measuring the weight of the LPG tank, then notify the user through NodeMCU
