Grove - HCHO Sensor Bargain F Both motors can be drivenThe Grove HCHO Sensor is a semiconductor VOC gas sensor. Its design is based on 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 has a very high sensitivity and stability, it can detect the gas whose concentration is up to 1ppm. It's suitable for detecting formaldehyde, benzene, toluene and other
