EnoPuck® CO2

The “EnoPuck CO2” CO2 traffic light can be used both as a stand-alone solution and in conjunction with a building automation system. Unlike many other solutions, the bright RGB LEDs make the light signal clearly visible at all times, even from a greater distance. The CO2 measured value is measured and displayed in the individual solution in the form of a traffic light (green/yellow/red), whereby the limit values can be configured using the BL-PC-FLEX-2 software. The integrated motion detector also enables the LEDs to be switched off when no one is in the room.

The measured values at a glance

The EnoPuck® CO2 delivers the following measured values via EnOcean telegram at configurable intervals:

Measuring range: 0 – 2,550 ppm (others on request) Accuracy: +/- 30 ppm +/- 3% of the measured value Repeatability: 10 ppm Temperature stability: 2.5 ppm / °C (0 .. 50°C)
Measuring range: 0°C .. 50° C Accuracy: +/- 0.5 °C Repeatability: 0.1 °C Note: Due to self-heating, it takes some time for the measured value to settle.
Air humidity
Air humidity
Measuring range: 0 .. 95 % rel. hum. Accuracy: +/- 2 % Repeatability: 0.1 % rel. Hum.
PIR motion detector Range approx. 2.5 m Opening angle approx. 120°
Ready for immediate use

The measured values

The EnoPuck CO2 delivers measured values for CO2, humidity, temperature and the status of the motion detector (0/1) every 60 seconds ex works.

With the factory default setting, the EnoPuck CO2 continuously supplies new measured values via EnOcean every 60 seconds.


External plug-in power supply unit

The EnoPuck CO2 requires an external plug-in power supply with 12 V DC voltage, especially for operating the internal LEDs. This is already included in the scope of delivery. On this basis, however, you can also configure the measuring interval for the CO2 measured value to a quick 10 seconds, for example. This enables more precise data analysis than is possible with solar-powered devices.

The EnoPuck CO2 sends the data ex works under two different device profiles. You can also switch them on/off separately and change the transmission intervals manually if required.

CO2 traffic light and measurement data acquisition

The EnoPuck CO2 comes to you pre-configured and ready to use. The measurement starts as soon as the external power supply unit is connected. Depending on the measured CO2 concentration, the LEDs light up in green, yellow or red.
Maintenance and care

Calibration of the sensor

A CO2 sensor with the sensor type / measuring principle we use is precise, but also relatively sensitive to shocks and vibrations. If the measured value is no longer apparently correct, you can simply recalibrate the sensor at any time. To do this, press the service button on the device, e.g. with a paper clip, for >10 s until the EnoPuck CO2 flashes blue. Calibration takes place after 10 minutes. The sensor now lights up green continuously. Now switch the power supply on/off once and the EnoPuck CO2 will work again.
