Temperature sensor SHELLY DS18B20

Shelly DS18B20 is an accurate and waterproof temperature sensor designed for measuring the temperature of indoor air, water, heating pipes, and other applications, while also allowing the measurement data to be used in home automations. Its wide measurement range of -55 to +125 °C and IP68-rated stainless steel sensor probe make it suitable for use in a variety of environments. The sensor connects to the Shelly Plus Add-on module, allowing temperature data to be monitored through the Shelly Smart Control app. Available with a 1 or 3-meter cable!

Shelly DS18B20 enables a wide range of temperature-based automations, such as automatically switching on heating when the temperature drops or switching it off once the target temperature is reached. The sensor can also be used to monitor the temperature of aquariums and hot water tanks, for example. The compact sensor probe fits into tight measurement spaces, and the sensor receives the power it needs from the connected Shelly device without requiring a separate power supply. Three-year (36 months) warranty!
