Temperature sensor DS18B20 (1 metre)

The DS18B20 temperature sensor with a 1 metre cable is a precision digital accessory, compatible with Shelly devices that offer a dedicated input for this type of sensor, such as the Plus Add-on or other Shelly modules with DS18B20 support. The 1 metre cable is suitable for installations where the measuring point is close to the main Shelly device, such as inside an electrical panel or a technical enclosure.

The DS18B20 digital sensor provides precise temperature readings, sent directly to the Shelly device it is connected to, and can be used in automations such as starting a recirculation pump at a certain water temperature, monitoring a water heater, a greenhouse or an industrial freezer/fridge.

As a wired sensor, its moisture-resistant housing allows installation in more demanding environments, such as the outside of a house, a cellar or next to a water pipe, where direct temperature measurement is needed for precise automations.

Please note: this sensor requires a Shelly device compatible with a DS18B20 input in order to be used; it does not work on its own and does not connect directly to WiFi.

Practical use cases

• Attaches to compatible Shelly devices to measure the temperature of a liquid or a surface (water heater, boiler, pipe), not just the ambient temperature.
• Useful for monitoring the temperature of domestic hot water or a heating system, with alerts in case of overheating or excessive cooling.
• The 1 metre cable allows the sensor to be mounted a little further from the Shelly module, exactly where the measurement is needed.
• Can be used in automations that switch equipment on or off depending on the measured temperature (e.g. recirculation pump).

Technical specifications

With its 1 metre cable, this sensor is ideal for compact installations where the Shelly device and the measuring point are in the same area.
