Product Description

Details

Introduction
The gas sensitive material used in the MQ-2 gas sensor is SnO2, a low electrically conductive material in clean air. When there is combustible gas in the surrounding air, the electrical conductivity of the sensor will increase with the higher intensity of the combustible gas. Here, we can convert the changing electrical conductivity into output signal by building a simple circuit

Main Features
1.Detected Gas: Combustible Gas, Smoke;
2.Detection Intensity: 300~10000ppm(Combustible Gas);
3.Working Voltage: 5.0V±0.1V AC or DC;
4. Preheating Time: ≥2 minutes.

Package Including
1 x MQ-2 Gas Sensor Module.

Works fine, By Eliasa 2019-12-16 07:06:12

Works fine, but a bit difficult to properly calibrate if you're looking to use it as a breathalyzer.
