Air Quality Monitoring using NodeMCU and MQ2 Sensor - IoT ...

· Generally, for gas leakage detection (home and industry), we will use the MQ2 module. It is suitable for detectingH2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to the high sensitivity and fast response time of it. But, in this design, we used the MQ2 sensor for the smoke situation. This sensor has four outputs, namely, Vcc, ground, D0, and A0.
