Sensor CO2 1W-UNI


CO2 & Temperature & Humidity sensor (300–40 000 ppm, 0 to +50°C, 0 to 95% RH), indoor box. 3 m of cable is included. Plug the sensor into the RJ11 1W-UNI (3 sensor values).
SKU: 600746 Categories: ,


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, a ceiling, or 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 RJ11 jacks is used for the connection. Connection cable (3 m) is included in the package.

  • Communication interface: 1-Wire UNI (RJ11)
  • Maximum length from the active 1-Wire port: 30 m
  • Temperature measurement: In the range -0 to +50 °C, accuracy: 0.8 °C
  • Humidity measurement: In the range 0–95% RH (Relative Humidity),
  • Measurement CO2: In the range 300 to 40000 ppm
  • 5V power from the 1-Wire port
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.

Installation and use

  1. Connect the sensor to any HW group monitoring device (RJ11 cable included).
  2. Switch on the device’s power & search for the sensors.
  3. Temperature and humidity values are available immediately.
  4. The internal CO2 sensor needs to be calibrated in the environment. The calibration takes 7 days; during this time, it is necessary to air the premises regularly and thoroughly, at least 3 times a day.
