Is there sufficient fresh air supply?People produce CO₂ or carbon dioxide while breathing. That makes CO₂ concentration a good indicator for the occupancy and activity level in a space. In many applications, CO₂ sensors are used as an indicator for the ventilation requirements. This HVAC transmitter offers a clear, visual indication of the CO₂ level via the green, yellow and red LED. The green LED indicates that the CO₂ level is within range - there is sufficient fresh air supply. When the CO₂ level enters the alert range, the yellow LED lights up. Red means: CO₂ out of range or insufficient fresh air supply. The measured temperature, relative humidity and CO₂ level are available via the three analogue outputs and via Modbus RTU. The dew point and ambient light level are available via Modbus RTU.

NDIR sensor technologyNDIR or Nondispersive Infrared technology is used to measure the CO₂ level. This technology offers a low life-cycle cost and a precise and stable long-term operation.

This sensor has three analogue outputs. Each of them transmits one of the measured values. E.g. by default, output 1 will transmit 0 V at 0 °C and 10 V at 50 °C. Each output value varies proportionally in function of the measured temperature, humidity or CO₂ concentration. The measured temperature is available via output 1, relative humidity via output 2 and CO₂ concentration via output 3.Easy to use!This sensor doesn't require configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU.E.g. a different output type can be selected to make it compatible with other devices: 0-10 VDC / 0-20 mA / 0-100 % PWM.  Also the light intensity of the LEDs for status indication is adjustable. The Modbus register map provides a complete overview of all adjustable settings.

3-wire connectionThis sensor can be supplied with 24 VDC or with 24 VAC. It is intended for 3-wire connection. The ground of the output (GND) is internally connected to the ground of the supply voltage (V-). Make sure not to connect this common ground to other devices that are powered by a DC voltage.

Self-calibrating to compensate sensor driftThe ABC logic self-calibrating algorithm is by default enabled. This algorithm is designed to be used in applications where CO2 concentrations will drop to outside ambient conditions (400 ppm) at least one time (15 minutes) in a 7day period, which is typically seen during unoccupied periods. The sensor will reach its operational accuracy after 25 hours of continuous operation at a condition that it was exposed to ambient reference levels of air at 400 ppm ± 10 ppm CO₂.
