Description: Gas/smoke leakage –Using the MQ-2 gas / smoke leakage sensor,  Arduino  Uno and GSM  sim900A module,  this tutorial is based on the detection of gas smoke leakage or smoke detection. This project is used to detect gas/ smoke when a message is sent to the owner once the gas/smoke leakage is detected. This can be used in kitchens, rooms, etc. to provide the best possible protection The Gsm sim900A and MQ-2 sensor interfacing with Arduino Uno or Mega is very simple. I’ll show you need to make your own Gas/smoke leakage detection system … Continue reading Arduino Gas/smoke leakage detection and sms alert system programming
