API for the DFRobot MQ8 Hydrogen (H2) Gas Sensor. More...

Detailed Description

The MQ8 Gas Sensor module is useful for detecting Hydrogen gas concentrations in the air. It has a detection range of 100-10000 ppm.

For optimum use, it requires calibration after a pre-heat time of at least 24 hours. See the datasheet for details.
