This is a smart system for detecting gas levels using the Internet of Things (IoT). When the gas concentration in the environment exceeds a predetermined threshold, a notification will be sent to the smartphone through the Blynk app. The system also offers two modes for managing the gas detection process: manual or automatic mode.

- Auto Mode : Fan turns on once the gas level is in maximum PPM (55 above)
- Manual Mode : Fan is controlled by user through Smart phone with Blynk App

Blynk will display LPG PPM rates through the Blynk app. If the PPM of the gas is the maximum than the PPM should be. Blynk will notify users, and the LEDs on Blynk will turn RED
