Room humidity, temperature and CO2 sensor or measuring transducer AERASGARD® FSFTM-CO2-Modbus

TheAERASGARD® FSFTM - CO2 - Modbus room sensor and measuring transducer with in-wall housing and optional potentiometer is used to measure The CO2 content, relative humidity and temperature of the air, and for setpoint adjustment. The measured values are queried via the Modbus interface.

The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra- red technology). A digital, long-term stable sensor is used for humidity and temperature measurement. Relative humidity [% r.H.] is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature.


The in-wall transmitter is mounted either individually or in combination with light switches, socket outlets, etc. in high-quality panel switch brand programmes, such as preferably from Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (with in-wall adapters, no setpoint adjustment possible).
