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

Grove - HCHO Sensor _RaspberryPi Power consumptionThe 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
