HW-group Sensor CO2 1W-UNI

Sensor CO2 1W-UNI is a combined Temperature (-0 to +50 °C), Relative Humidity (RH 0-95%) and CO2 (300 - 40000 ppm) sensor in one box for the indoor environment. Can be connected via RJ11 interface (1-Wire UNI bus) with all HW group monitoring devices.

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 it can be secured in place with a piece of double-sided adhesive tape. A detachable cable with RJ-11 jacks is used for the connection. Connection cable 3m included in the package.


Applications and usage:

Thanks to its ability to monitor CO2, Temperature, and RH (Relative Humidity), this sensor can be used in many areas. In addition to monitoring air quality in households, commercial buildings and school buildings, it will also help you in various measurement and regulation projects
