Grove - HCHO Sensor _RaspberryPi They tend to draw ~30mA

They tend to draw ~30mA or so in practice but for precise numbers you must measure the current in your usage circuit

This wire is not designed explicitly for outdoor use so it will fade if continuously exposed to UV

Included Parts for Electronic Projects:

Tri-point - Y000

Grove - HCHO Sensor _RaspberryPi They tend to draw ~30mAThe Grove HCHO Sensor is a semiconductor VOC gas sensor. It uses the VOC sensor WSP2110 whose conductivity changes with the concentration of VOC gas in air. With a circuit, the conductivity can be converted to an output signal that corresponds 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 can be used to detect Toluene, Methanal, Benzene, Alcohol, Acetone
