LPG Gas Leakage Detector Using Node MCU With Blynk ...

Here we use an MQ-2 gas sensor that detects the LPG, Alcohol, Smoke, etc, gases. If there is a gas in the air the resistance between two electrodes of the gas sensor gets increased according to the gas presence. We use node MCU as a microcontroller or a wifi development board that reads the analog values from the gas sensor. In the code, we set the gas value [200]. The node MCU sends these ...
