My opinion about VOC Sensors – See The Air

Jun 20, 2016· Blowing right into *any* sensor will probably mess up its current measurement, be it temperature, humidity, co2 or voc sensor. Many voc sensors in air quality home devices are just cheap low quality crap like estimating voc from co2 concentration and not direct measuring this is why breathing elevates it as well or complete junk that gives nonsense values.
