Data Sheet


The PreonCube Condition CO2 is a wireless radio measuring point with external CO2 sensor. Due to its compact design, the Cube is very well suited for monitoring rooms, buildings, warehouses, cabinets or hard-to-reach environments. Depending on the selected measuring interval, the Cube uses its sensor to record data on the CO2 concentration and can be used with or without a power supply unit. Depending on requirements, it transmits the measured values at customer-specific intervals and a suitable radio protocol to other measuring points or directly to radio gateways. From the optionally available gateways, the data is transferred to the PreonLive online portal where it can be analyzed and exported. So you can monitor your remote CO2 cubes from any PC, smartphone or tablet with Internet access and have an overview of their current measured values at all times. The radio traffic light PreonCube Condition Signal Light is available to match the PreonCube Condition CO2. The three-stage traffic light can be operated within radio range of the measuring point and, depending on the CO2 concentration, signals the current measured value range with different colours and thus forms a CO2 traffic light.


An external sensor with infrared technology (NDIR) is used to record the data. This is equipped with a filter cap and is located on the upper side of the cube. It measures with high accuracy the concentration of C02 in ambient air from 0ppm to 5000 ppm.


  • Areas of application: seminar rooms, buildings, storage, occupational health and safety, indoor climate

  • Use: Monitoring of buildings, halls, rooms, cabinets or showcases, etc.

  • Monitoring, detection, control and alarming

  • Random checks or long-term measurements
