Digital temperature sensor TST103

Model TST103

Short Description

The TST103 is a digital temperature sensor with a 1-Wire interface. It is an excellent solution for temperature monitoring and control.

It focuses on applications that require precise temperature monitoring – server rooms, offices, drug and food stores, etc. It is suitable for smart office applications, as well as for data loggers and thermostats.

A special accessory, allows easy installation in 19” cabinets, and can be ordered separately.

The digital temperature sensor provides high measurement accuracy as low as ±0.5°C in -10 to +85°C range. It opperates with 12 bit precision from the onboard digital-to-analog converter. The supply voltage is from 3 to 5.5VDC. The current draw is less than 2mA.

The TST103 communicates with controllers over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows multi-sensor support over the same 1-Wire bus. The digital temperature sensor utilizes two RJ11 connectors for easy daisy chain wiring.

The digital temperature sensor can be used with

* Ethernet IO module TCW241
* Ethernet data logger TCW220
* Remote IO module TCW122B-CM
* GSM-GPRS remote monitoring controller TCG120
* IP watchdog monitoring module TCW122B-WD
* Remote environmental monitoring module TCW112-CM
* IP watchdog relay board TCW112-WD
