Where to use the sensor
The Cobra Climate Sensor is designed for indoor use in spaces where people are (occasionally) present. A typical deployment is one or two sensors per room. The sensor measures indoor climate data only: CO₂, temperature, humidity and air pressure.
Placement guidance
For accurate, representative readings, follow these rules when positioning the sensor:
- Mount it as far as possible from ventilation openings — air moving directly past the sensor distorts the CO₂ reading.
- Mount it on a wall, where there is no direct contact with people or animals.
- Mount it at a height between 1.20 and 1.80 metres.
- Do not mount the sensor on a ceiling.
Installing the sensor
The baseplate has mounting holes so you can fix the sensor to a wall or near a wall socket.
- Fix the baseplate to the wall using the mounting holes.
- Connect a quality USB power supply. The connector is hidden inside the casing.
- Click the sensor onto the baseplate.
As an alternative, you can power the sensor from an embedded USB power supply built into a wall socket.
Power requirements
- USB powered, 5V (minimum 4.9V measured at the end of the cable).
- Energy use is below 1 watt — typically around 600 mW.
Once the sensor has power, continue with Getting started with a pre-configured sensor.
