what is mq2 smoke sensor

smart smoke detector using IoT | iot smoke detector

· This article will make our own smart smoke detector with an MQ2 gas sensor and NodeMCU. We can call it smart as it automatically detects the smoke and sends an alert notification to our smartphones. For controlling the MQ2 gas sensor we are using the Blynk app. Please check how you can set up your Arduino IDE to upload the code in NodeMCU.

TECHNICAL DATA MQ-2 GAS SENSOR

The sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorin. Touch water Sensitivity of the sensors will be reduced when spattered or dipped in water. Freezing Do avoid icing on sensor’surface, otherwise sensor would lose sensitivity.
