The Smart Radon Sensor offers a very high sensitivity in a very small and shapely housing. Due to the detector technology, the instrument will not be affected by any variations of temperature and humidity, external radiation, mechanical shocks and vibrations. The measurement starts as soon as the power is connected.

SMART RADON SENSOR – the smart solution for building automatization systems

Various interfaces for system integration are available. The RS485 network interface can be operated either with the MODBUS RTU (industrial standard) or the proprietary SARAD protocol. The analogous output makes it easy to connect the Smart Radon Sensor to existing PLC’s. A stand-alone ventilation control system can be easily realized by the alert switch output. If no data line is available, the optionally integrated ZigBee wireless interface can be used for connection to a host system. The wide range of power input accepts all in building automation commonly used voltage supplies. For easy installation, all connections are available through a screw terminal.
Two AAA batteries are integrated to continue the measurement in case of power interruptions. All measurement results will be stored locally in non-volatile circular memory.
Sensors for temperature and humidity are integrated as a standard. The Smart Radon Sensor comes with factory calibration and can be calibrated by any responsible accredited laboratory.
This product is manufactured in SARAD company’s location in Dresden/Germany.
