The Shelly DS18B20 Temperature Probe is a 1-Wire digital temperature sensor for the Shelly Uni or the Shelly Plus Add-On Sensor Interface. Needing only one pin to connect, you can connect up to 3 digital thermometers on a single microcontroller.

Features

• Digital Output

  The DS18B20 provides temperature data in digital format, making it easy to interface with microcontrollers and other digital devices.

• High Accuracy

  With an accuracy of ±0.5°C in the range of -10°C to +85°C, the DS18B20 provides reliable temperature measurements for a wide range of applications.

• Wide Temperature Range

  The DS18B20 can measure temperatures from -55°C to +125°C, suitable for both indoor and outdoor environments.

• Multiple Resolution Options

  It offers selectable resolutions ranging from 9 to 12 bits, allowing users to choose between higher resolution and faster conversion times according to their requirements.

• Single Wire Interface

  The DS18B20 communicates over a single wire (1-Wire protocol), simplifying the wiring and enabling multiple sensors to be connected to a single microcontroller pin.
