The combined sensor of Air quality (CO2), Temperature and Humidity in one small body for use with SD-2x1Wire and NB-2x1Wire IoT monitoring units and other HW group devices.  Sensor CO2 1W-UNI measures temperature (0°C to + 50°C), air humidity (0-95 %RH - Relative Humidity), and CO2 (300 - 40 000 ppm). 

Housed in a small elegant plastic box, this sensor can be mounted on a wall or a ceiling or placed on a desk. It is small and lightweight so can be secured in place with a piece of double-sided adhesive tape. A detachable cable with RJ11 jacks is used for the connection. Connection cable 3 m included in the package.
