Temperature, relative humidity, CO2, and ambient light level are all measured by this room transmitter. The CO2 level is visually indicated by the green, yellow, and red LED indicators.
The supply voltage is 24 V DC and can be connected using either the terminal blocks or the RJ45 connector. The measured values are communicated via three analogue outputs and Modbus RTU.
The output type is set to 0-10 V by default but various output types are available. Ambient light detection is used in many applications to control the ventilation system based on the occupancy of the room. Modbus RTU communication allows for the adjustment of all settings.
The CO2 sensor element can be replaced. The light intensity of the LEDs used for status indication can also be adjusted. This CO2 meter is commonly used in schools, office buildings, restaurants, and other public places to measure carbon dioxide levels and to ensure that adequate fresh air is supplied into the room.
