Grove HCHO Sensor Arduino

Grove HCHO Sensor Arduino

The Grove - HCHO Sensor is a semiconductor VOC gas sensor. Overview. Its design is based on the WSP2110 whose conductivity changes with the concentration of VOC gas in air. Through the circuit, the conductivity can be converted to output signal that corresponding to the gas concentration. This sensor can detect the gas whose concentration is up to 1 ppm.
