Sensor CO2 1W-UNI is a combined Temperature (-0 to +50 °C), Relative Humidity (0–95% RH) and CO2 (300–40000 ppm) sensor in one box for the indoor environment. It 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, ceiling, or placed on a desk. It is small and lightweight so it can be secured in place with double-sided adhesive tape. A detachable cable with RJ11 jacks is used for the connection. A 3m connection cable is included in the package.

Features:

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

Applications and usage:

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

Installation and use:

• Connect the sensor to any HW group monitoring device (RJ11 cable included)
• Switch on the device power & search for the sensors
• Temperature and humidity values are available immediately
• Internal CO2 sensor requires calibration in the environment. The calibration takes 7 days; during this time, air the premises regularly and thoroughly at least 3 times a day
