Project Explanation

   This is the mini-project which we have done successfully. This is a Live Real-Time Project designed at low cost with high accuracy. It is easy to implement. This is very much cost effective when compared to other devices in online. This Project is designed to detect the LPG Gas Leakages and to alerts the users through Audio-Visual Indications. This Project is designed to detect the LPG & 4 other Dangerous Gases from a range 200(PPM) to 10,000 PPM. We used MQ-4 gas sensor. Whenever there is LPG concentration of 1000 ppm (parts per million) in the area. A buzzer is connected to produce audible alert signal. This LPG Gas Sensor can be used to make wireless Gas leak detector in home security system .
