Sensor THPVoc 1W-UNI


Temperature, Humidity, atmospheric Pressure, TVoc sensor (-30 to 70 °C, 0 to 100% RH, 300 – 1 000 hPa, 0 – 60 000 ppb), indoor box. 3m cable included. Plug as sensor to the RJ11 1W-UNI (4 sensor values).
SKU: 600747 Categories: ,


  • Sensor THPVoc 1W-UNI measures temperature (-30 to +70 °C)  and air humidity (0–100% RH, relative humidity), as well as atmospheric pressure (30 000 to 110 000 Pa) and air quality (00 to 60 000 ppb) concentration of volatile organic compounds (TVOC). 

    The volatile organic compounds sensor detects the TVOC concentration in the air (in ppb, parts per billion).

    Temperature, humidity, atmospheric pressure, and a TVOC sensor are housed in a small, elegant plastic box and can be mounted on a wall, a ceiling, or 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) is included in the package.

    • Communication interface: 1-Wire bus, RJ11 jack
    • Maximum length from the active 1-Wire port: 30 m
    • Measurement range: -30 to +70 °C, resolution: -0.1 °C
    • Humidity measurement in range: 0–100% %RH (Relative Humidity)
    • Atmospheric pressure measurement in the range: 30 000 – 110 000 Pa
    • Air quality measurement in the range: 0 – 60 000 ppb
    • 5V power from the 1-Wire port
    Applications and usage:

    Thanks to its flexibility, this sensor is ready for integration into air conditioning systems, intelligent building management systems, schools and residential homes. The atmospheric pressure sensor is useful for weather forecasting or for detecting loss of pressure in positive or negative pressure rooms.

    Installation and use

    1. Connect the sensor to any HW group monitoring device (RJ11 cable included).
    2. Switch on the device’s power and search for the sensors.
    3. Temperature, relative humidity, and air pressure values are available immediately.
    4. The TVOC sensor needs to be calibrated in its environment. The calibration takes 10 days; during this time, it is necessary to air the premises regularly and thoroughly, at least twice a day. Moreover, the values in ppb only become available 10 seconds after the sensor is powered up.
