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

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

The Temperature, Humidity, Atmospheric Pressure, and TVOC sensor is housed in a small elegant plastic box and can be mounted on a wall or 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 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 range: 0–100 %RH (Relative Humidity)
• Atmospheric pressure measurement range: 30,000–110,000 Pa
• Air quality measurement 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:

• Connect the sensor to any HW group monitoring device (RJ11 cable included)
• Switch on the device power and search for the sensors
• Temperature, relative humidity, and air pressure values are available immediately
• The TVOC sensor requires calibration in its environment (10 days). During this time, air the premises regularly and thoroughly at least twice a day
• Values in ppb only become available 10 seconds after the sensor is powered up
