Project Description

Short Description

TST103 is a digital temperature sensor with 1-Wire interface. It is excellent solution for temperature monitoring and control. It focuses on applications that require precise temperature monitoring – server rooms, offices, stores etc. It is also suitable for smart home applications, as well as for data loggers and thermostats. A special accessory, allows easy installation on 19” cabinets, can be ordered separetely.

The digital temperature sensor provides high measurement accuracy as low as ±0.5°C in -10 to +85°C range, working with 12 bits of precision from the onboard digital-to-analog converter. Its current consumption is lower than 2mA, while the supply voltage is from 3 to 5.5VDC.

TST103 communicates with controllers over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows multiple sensors support over the same 1-Wire bus. The digital temperature sensor utilizes two RJ11 connectors for easy daisy chain of multiply sensors systems. The sensor is supported by TCW11x, TCW12x, TCW220, TCW241 and TCG120 controllers.

  • Easy daisy chain connection;
  • Unique 64-Bit serial number for multiply sensors support;
  • ±0.5°C accuracy from -10°C to +85°C;
  • 12 bits resolutions.

  • Server rooms temperature monitoring;
  • Buildings thermostatic controls;
  • SCADA systems for temperature monitoring;
  • Temperature data loggers.
