Cigarette Smoke Detectors using ESP32

Many places such as school , hospitals are restricted to smoking. This will affects the normal health of the public. So we have developed a system which detects the cigarette smoke.Mq-2 gas sensor which is useful in gas leakage detection and detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. The sensor is connected with ESP8266 Microcontroller. If the sensor detects the smoke , it will sends the alert message to the respective person,.
