Room fine dust sensors from the AERASGARD® series enable continuous monitoring of indoor air quality. With optical precision sensors, they reliably detect the concentration of fine dust particles in various size classes (PM1.0, PM2.5, PM10) and thus actively contribute to health and well-being. The compact devices are ideal for offices, schools, nurseries, public buildings and living spaces. Depending on the model, analog output signals (0-10 V / 4-20 mA), digital interfaces or potential-free changeover contacts are available for integration into building automation systems.
