Shelly DS18B20 Waterproof Digital Temperature Probe

The Shelly DS18B20 temperature sensor is the right add-on for your SMART HOME if

you want to monitor the room temperature.

The DS18B20 Probe is the ideal instrument of the Shelly line to measure the

temperature of the environment in which it is located.

We use our probe by connecting it with the compatible ADDON chip for

Shelly 1 and Shelly 1PM .

With the sensor, the radiators in the living room can be optimally adjusted.

The heating works efficiently and at the same time you save on costs.

Suitable for outdoor use

The Shelly DS18B20 temperature sensor is equipped with a 1-wire interface.

As a result, the sensor only needs one port pin to communicate with a microcontroller.

Since the sensor has its own unique 64-bit address, it can work with one or two other sensors

on the same single-wire bus. Thanks to the cable length of 1 meter, you have sufficient leeway

when installing the temperature sensor.

Thanks to the stainless steel housing and waterproof cable , the sensor is also very suitable for outdoor use.

It does not require external power

The Shelly DS18B20 temperature sensor can derive its operating current directly from the data line.

Experts call this "Parasitic Power". This makes an external power supply superfluous.

Quick connection and installation in the smart home is possible with the quick start guide.

How to use it

Applications that can benefit from this feature include HVAC environmental controls,

temperature monitoring systems inside buildings,

equipment or machinery and process monitoring and control systems

Features and Functionality:

  • High quality stainless steel case
  • Cable length 1 meter
  • Perfect for shelly 1 or Shelly 1pm
  • For temperature ranges from -55 to 125 ° C


The temperature probe consists of three wires that start from it and that we are going to connect to

our SHELLY 1 and SHELLY 1PM to also have the data of the detected temperature.

Cavo un po’ corto
rating 5
Le sonde vanno bene e quasi sempre sono precise. Su grandi escursioni termiche perdono in
Precisione. Cavo un po’ corto ma si può allungare con un cavo di rete o telefonico senza problemi.
