The Grove HCHO Sensor (formaldehyde Detection), is a semiconductor VOC gas sensor. It uses the VOC sensor WSP2110 whose conductivity changes with the concentration of VOC gas in the air. With a circuit, the conductivity can be converted to an output signal that corresponds to the gas concentration. This sensor has very high sensitivity and stability, it can detect gas whose concentration is up to 1ppm. It can be used to detect Toluene, Methanal, Benzene, Alcohol, Acetone, etc. This product can be used to detect the presence of harmful gas in the home environment. It can be a good assistant to improve indoor air quality.
Highlighted Features
