Shelly Temp Sensor DS18B20

The Shelly Temp Sensor DS18B20 is a waterproof digital temperature probe designed for precise environmental monitoring in smart home applications. When connected to a Shelly Plus Add-on with Shelly 1 or Shelly 1PM, this sensor enables intelligent heating control and automated climate management throughout your property.

Featuring a high-quality stainless steel housing and waterproof construction, this temperature sensor is suitable for both indoor and outdoor use. The wide measurement range from -55°C to +125°C covers virtually any residential or commercial monitoring application. The 1-metre cable length provides flexibility in sensor placement while keeping the connected device in a convenient location.

The DS18B20 uses a 1-wire interface with a unique 64-bit address, allowing multiple sensors to operate on the same data bus for multi-zone temperature monitoring. The parasitic power feature draws operating current directly from the data line, eliminating the need for external power supply and simplifying installation. Connection is straightforward with three wires: red for VCC, yellow for DATA, and black for GND.
