Description
The TST103 is a 1-wire digital temperature sensor that can connect to a 1-Wire interface, making it ideal for monitoring and control in environments, such as server rooms, offices, and storage areas for temperature-sensitive goods. Its suitability extends to smart office applications, data loggers, and thermostats. For convenient installation in server environments, a specific accessory for 19” cabinets is available separately.
The TST103 sensor delivers high measurement accuracy of ±0.5°C within the -10 to +85°C range, employing 12-bit precision from its integrated digital-to-analogue converter. Operating with a low current consumption of under 2mA and a supply voltage range of 3 to 5.5VDC, the TST103 communicates via a 1-Wire bus. Each unit features a unique 64-bit serial code, enabling the use of multiple sensors on the same bus, and incorporates two RJ11 connectors for simplified daisy-chain wiring.

Compatible Controllers & Monitoring Systems
Designed for Seamless 1-Wire Networking:
The TST103 is engineered for high-density environmental monitoring. To function, this sensor must be connected to a compatible 1-Wire Controller (Master) featuring RJ11 ports. Its dual-port design allows for efficient linear daisy-chaining, reducing wiring complexity in server racks and industrial cabinets. The RJ11 ports also provide the power for the sensor.
Flexible Installation Options:
- Daisy-Chain Configuration: Connect multiple TST103 sensors in a sequence using 1m or 3m RJ11 patch cables for localized monitoring (e.g., across multiple rack levels).
- Direct Long-Range Connection: For sensors located further from the master unit, use the 30m RJ11 cable to connect a single sensor or the start of a chain directly to the controller.
- Maximum Network Reach: The system supports a total cable length of up to 30m in a linear topology, ensuring reliable data transmission across large data centres.
