The KSC 102 - CO2 sensor is designed to measure the concentration of carbon dioxide in the air in areas protected from water.

The KSC 102 - CO2 sensor consists of a plastic ribbed head where a printed circuit board with the CO2 sensor and a converter is placed to establish communication via the RS 485 bus. The CO2 value is measured by an NDIR module. whose digital signal is also converted into an output signal of MODBUS RTU. For the CO2 concentration sensor, an auto-calibration function is available to set the sensor to the minimum CO2 value corresponding to the outdoor concentration level. The KSC 102 - CO2 sensor meets the protection rating IP 30 according to EN 60529. Appropriate design and high quality material ensure that the sensor is not disturbing, even in interiors with high aesthetic requirements. You can choose the color of the box white or gray.

The KSC 102 - CO2 sensor is designed to operate in a chemically non-aggressive environment; its use should be chosen according to the temperature and chemical resistance of the head and the individual sensors. The operating conditions to establish the correct function are:

Ambient temperature near the sensor: 0 to 45 ° C

Ambient relative humidity: 0 to 95% (non-condensing humidity)

Atmospheric pressure: 87 to 106 kPa
