Electrical humidity sensors are measuring the relative air humidity, usually by a measuring element that changes the electric capacity proportionally to the air humidity.
The particulate-hygro-thermo-baro sensors from our COMPACT series are designed to measure relative humidity, air temperature and barometric air pressure, and particulate matter sensor (PM1, PM2.5, PM4, PM10, particle densitiy <0.5, <1, <2.5, <4 and <10 µm)
Weather stations, the combination of different sensors for relative humidity, air temperature and barometric air pressure, and particulate matter.
