MQ-7 Carbon monoxide gas sensor module

Description

MQ-7 Carbon monoxide gas sensor module detects the concentrations of CO in the air then outputs its
reading as an analog voltage. It can measure concentrations of 10 to 10,000 ppm. Additionally, it can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5V. It also uses SnO2 material, whose conductivity is lower in clean air. Its conductivity increases as the concentration of CO gases increases

Features of MQ-7 Carbon monoxide gas sensor module includes;

• Good sensitivity to Combustible gas in wide range
• High sensitivity to Natural gas
• Long life and low cost
• Also uses a simple drive circuit
• Power of 2.5V to 5.0V

Applications Includes;

• Carbon monoxide monitor
• Domestic gas leakage detector
• Industrial CO detector
• Portable gas detector
