The DS18B20 temperature sensor is a waterproof sensor suitable for both outdoor and indoor use. It is a digital temperature sensor with calibrated digital signal output. Thanks to its waterproof design, it can be reliably used in wet areas or environments, such as water tanks, aquariums, cold storage rooms, pools, etc. The sensor is made of stainless steel, ensuring a long lifespan and sensitivity to temperature changes. This version comes with a 3-meter long cable, which can be shortened if needed.
Note: Only the metal end of the sensor is waterproof.
The measured temperature range is from -55°C to 125°C, and it operates reliably in both high and low temperature conditions.
When connected to the Shelly Uni or Plus Uni, or used with Shelly 1 and Shelly 1PM (with the necessary sensor adapter), or Shelly PLUS series relays (requiring the Plus Add-On adapter), it is excellent for temperature measurement. The sensor can be connected to the relay after the smart device has been powered off. After that, the temperature measurement function can be activated in the Shelly app under the device settings.
