Project Description

Short Description

TST100 is 1-Wire temperature sensor for indoor and outdoor usage. It provides a low cost option for temperature monitoring for home and industrial automation. The head of the sensor is made of aluminum, allowing low thermal resistance to the controlled object. The sensor communicates over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows multiple sensors to function on the same 1-Wire bus.

TST100 measures temperartures in range from -40 to +85°C (-40 to 185°F). Used digital signal processing allows accuracy as low as ±0.5°C in -40 to +85°C range.

1-Wire temperature sensor is delivered with 1 meter cable, with soldered wires for direct connection to the screw terminals of controllers TCW1xx, TCW2xx and TCG1xx.

  • Requires no external components;
  • Each device has a unique 64-Bit serial number;
  • ±0.5°C accuracy from -10°C to +85°C;
  • 12 bits resolutions.
