Analog Hydrogen Gas Sensor MQ8

Grove - Air quality sensor V1.3

This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

Grove – Multichannel Gas sensor is a environment detecting sensor with a built in MiCS-6814 which can detect many unhealthy gases. 3 gases can be measured simultaneously due to its three channels, so it can help you to monitor the concentration of more than one gas.

Sensor based on infrared non-dispersive technology ( NDIR ). It has good selectivity and dependence without oxygen. Integrates temperature compensation and support for UART communication mode.
