Description
DFRobot has released a gas concentration sensor for hydrogen and nitrogen oxide. The sensor utilizes MEMS technology to detect the concentration of gases including CO, CH4, C2H5OH, C3H8, C4H10, H2, H2S, and NH3. The accompanying sample code includes conversion formulas for different gas concentrations, making it easier to test and use the sensor. The product is compatible with 5V power supply, offers analog voltage output, and includes power supply enable/disable pins to reduce power consumption.
