This is a hydrogen and nitrogen oxide gas concentration sensor launched by DFRobot.

The sensor uses MEMS technology to support gas concentration detection of CO, CH4, C2H5OH, C3H8, C4H10, H2, H2Sand NH3. The matching sample code integrates the concentrationconversion formula of various gas to facilitate the testing and useof sensors.

The product supports 5V power supply, analog voltage output, and has power supply enable/disable pins for low power consumption.
