Sensor for detecting temperature, relative humidity, CO2, and ambient light level in HVAC systems. The supply voltage is 24 V AC or 24 V DC. The green, yellow, and red LED indicators indicate the CO2 level.
The measured values are transmitted via Modbus RTU communication and three analogue outputs. The output type is set to 0-10 Volt by default but there are various output types available. Using ambient light detection, the ventilation system can be controlled based on room occupancy. All parameter settings can be adjusted using Modbus RTU communication. The light levels of the LEDs used for status indication can be adjusted.
This carbon dioxide sensor is commonly used to monitor carbon dioxide levels in schools, offices, and restaurants, among other places.
