Product Description

Introduction

The gas sensitive material used in MQ-7 gas sensor is SnO2, which is of lower electrical conductivity in clean air. It detects carbon monoxide with low temperature (heated by 1.5V) through high-low temperature cycles. The electrical conductivity of the sensor increases with the increase of the carbon monoxide concentration in the air. The change of electrical conductivity can be converted to the output signal corresponding to that of the gas concentration by using a simple circuit.

The sensitivity of MQ-7 gas sensor to carbon monoxide is quite high, so it can be used to detect various gas containing carbon monoxide. It is a low-cost sensor suitable for a variety of applications.

Application

household gas leak alarm
Industrial-level carbon monoxide gas alarm
Portable gas detector
