MQ-3 Alcohol Gas Sensor Module Previous 
MQ-8 Hydrogen Gas Sensor Module is designed for sensing hydrogen gas with lower conductivity in clean air. As hydrogen gas increases, the sensor’s conductivity rises along with gas concentration. It provides an analog resistance output and supports conversion of conductivity change into a corresponding gas concentration signal through a simple circuit. This module offers high sensitivity to hydrogen gas and anti-interference to other gases. It is a low-cost sensor for gas detection applications.
