AERASGARD® FSFTM-CO2-Modbus P

The room climate sensor and transducer AERASGARD® FSFTM - CO2 - Modbus in a flush-mounted housing, optionally with potentiometer, is used to measure the CO2 content, relative humidity and temperature of the air and to set the target values. The measured variables are queried via the Modbus interface.

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


The flush-mounted sensor is installed in high-quality surface switch programs, preferably from Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using a flush-mounted adapter, no setpoint possible), either individually or in combination with light switches, sockets, etc.

It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, in interiors such as living rooms, offices, hotels, etc.
