The 1W-T-IB2 sensor is designed for interior measurements of temperature and relative humidity in buildings. Its circuit board is placed within an on-wall box (IP30 protection). The sensor can be also placed within a universal wiring box (KU68).

The sensor communicates with the master system using the 1-Wire bus (screw terminal, four conductors) and is fully compatible both with the Mervisan officially supported SW platform for Unipi products, and with the EVOK, an open-source application programming interface (API). For more info about the available software, please visit Unipi Knowledge Base.

  • Mervis: The sensor is based on the DS18B20 chip used in other 1-Wire thermometers on the Unipi e-shop and is used in the same way.
  • EVOK: The sensor is detected automatically and can be used right away. Measured values are accessible on an address of the particular sensor also serving as a device identification. You can find the address on a sticker provided with the product. 

The installation guide and technical parameters can be found in the product's datasheet (see the Files tab above).
