Description

This is a hydrogen and nitrogen oxide gas concentration sensor. The sensor uses MEMS technology to support gas concentration detection of H2, NO2 and NO. The matching sample code integrates the concentration conversion formula of various gas 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.
