Teracom TST103 is a digital temperature sensor with a 1-Wire interface and a working range from -40 to +85 °C

The TST103 is an excellent solution for temperature monitoring and control. It focuses on applications requiring precise temperature monitoring - server rooms, offices, drug and food stores, etc. It is also suitable for smart office applications, as well as data loggers and thermostats.
A special accessory, which allows easy installation on 19" cabinets.
The digital temperature sensor offers high measurement accuracy up to ±0.5 °C in the range from -10 to +85 °C. It operates precisely thanks to the on-board 12-bit digital-to-analog converter. Current consumption is less than 2 mA, while the supply voltage is between 3 and 5.5 VDC.
The TST103 communicates with controllers over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows support for multiple sensors on the same 1-Wire bus. The digital temperature sensor uses two RJ11 connectors for easy daisy-chaining.
