Teltonika 1-wire DS18B20 Temperature Sensor

The temperature sensor is designed for systems that require digital temperature measurement through a 1-Wire interface. This interface keeps communication simple by allowing temperature data to be transmitted over a straightforward connection, making the sensor suitable for applications where compact wiring and direct integration are important. The product supports operation across a wide temperature range from -55°C to +125°C, allowing it to measure both very low and high temperatures within the stated limits. Measurement accuracy depends on the temperature range. The sensor provides ±0.5°C accuracy from -10°C to +85°C, which makes this range the most precise operating band for applications where tighter temperature monitoring is required. Outside that band, the thermometer error is specified as ±1°C from -30°C to +100°C and ±2°C across the full -55°C to +125°C range. This helps users understand how measurement precision changes depending on the monitored environment.

The sensor is designed for straightforward electrical integration and operates from a 3.0V to 5.5V power supply range. This low-voltage requirement makes it suitable for compatible electronic systems that provide power within this range. Parasitic connection is supported, giving installers an additional supported wiring option where applicable. No external components are required for connection, which simplifies installation and reduces the number of parts needed around the sensor. This is useful in compact systems where minimizing additional components helps keep the design cleaner and easier to assemble. Combined with the 1-Wire interface, the sensor provides a practical solution for adding temperature measurement to compatible devices without introducing a complex wiring or component layout.
