The Siemens fine dust room sensor designed to measure and transmit indoor concentrations of PM2.5 and PM10. It operates on an AC/DC 24V voltage and provides a signal output of DC 0-10V for PM2.5 and PM10. With its communicative output, Modbus RS485, it offers easy integration into existing systems. The sensor has a range of use from 0 to 50 °C and 5 to 95% relative humidity, making it suitable for various environments. It also has an energy efficient mode that turns off the screen when no obstacle is in front of the sensor. The sensor supports multiple languages and selectable Air Quality Index classes, providing flexibility and convenience.
