The 1W-T-IB compact sensor is designed for interior temperature measurements in buildings. Its circuit board is placed within an on-wall installation box (KU 68 wiring box, IP30 protection). The sensor communicates with the master system using the 1-Wire bus (spring terminal, four conductors). 

The sensor is fully compatible both with the Mervis IDE, an officially supported SW platform for Unipi products and with the EVOK, an open-source application programming interface (API). 

  • 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. 

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