Shelly DS18B20 Temperature sensor with 3

The DS18B20 temperature sensor is a waterproof sensor suitable for outdoor and indoor use. It is a digital temperature sensor with a calibrated digital output signal. Due to its waterproof design, it can be reliably used in wet rooms or environments such as water tanks, aquariums, cold stores, swimming pools, etc. The sensor is made of stainless steel, which ensures a long service life and sensitivity to temperature changes. This version is supplied with a 3 metre cable which can be shortened if necessary.

Note: Only the metal end of the sensor is watertight.

The measuring temperature range is -55 °C to 125 °C and it works reliably at both high and low temperatures.

When connected to Shelly Uni or Plus Uni or used with Shelly 1 and Shelly 1PM (with sensor adapter required) or Shelly PLUS series relays (Plus Add-On adapter required), it is excellent for temperature measurement. The sensor can be connected to the relay when the smart device is switched off. You can then activate the temperature measurement function in the Shelly app under device settings.
