Abstract

The system consists of an MQ2 gas sensor connected to an ESP8266 (NodeMCU) microcontroller, which detects gas leakages by sending alerts to users through the Blynk IoT platform. The ESP8266 performs Wi-Fi connection after start-up, then proceeds to read gas levels through its analog input. The sensor value is read by the system once every 2 seconds before it sends the data to the Blynk application. When gas concentration surpasses the set limit, the system creates an alert that switches off the LED light and activates the relay or motor equivalent to an exhaust fan or buzzer and sends immediate notifications to users through Blynk. When the gas measurement shows safety, the system activates the LED light while keeping the motor powered down. Remote monitoring occurs indefinitely because this configuration allows instant notification of gas leaks.
