This is a hydrogen and nitrogen oxide gas concentration sensor module using a MiCS-2714 sensor.
The sensor uses MEMS technology to support gas concentration detection of NO, NO2 and H2.
The matching sample code integrates the concentration conversion formula of various gasses to facilitate the testing and use of sensors. The product supports 5V power supply, analog voltage output and has power supply enable/disable pins for low power consumption.
