Показать описание
Today we will make an IoT based smoke and gas detector using an MQ2 Sensor, ESP8266 microcontroller, and Blynk IoT Cloud. We have used the MQ2 Gas sensor module to detect Smoke, LPG, and carbon monoxide concentrations in Air. MQ2 is a versatile sensor that can detect LPG, smoke, alcohol, propane, hydrogen, methane, carbon monoxide, etc. This makes the MQ2 Gas Sensor Module an excellent choice for building an indoor air quality monitoring system, a breathalyzer, or an early fire detection system.

First, let’s see how this project works. The sensor detects smoke, LPG, and Carbon Monoxide values and sends them to ESP8266 Microcontroller. Then it processes these values and displays them on the OLED display and on the Blynk IoT Platform. It also checks if these values are above the safe level then it sends a notification to the Mobile phone and the buzzer starts alarming with a flashing LED.
