Infrared CO2 sensor

Mod CO2 sensor Assesses occupancy level in a room by measuring the CO2 content. Easy to install. Just 3 wires needed for data + power supply. Automatic re-calibration – no maintenance. Well-suited to large volume spaces. Single zone and multiple zones. Principle: measure absorption of infra-red rays to determine CO2 concentration in a room. CO2 measurement not affected by dust and water vapor. Sensor measurement range: 0 to 2000 ppm. Trip level: 1100 ppm by default (can be adjusted to between 700 and 1700 ppm by increments of 200 ppm using a selector switch). Output signal proportional to ambient concentration measured. Response time < 7 minutes. Sensor power consumption: 500 mA.
