Temperature digital sensor DS18B20 metal, 3m

# Universal digital temperature sensor

Universal digital temperature sensor (**DALLAS DS18B20 clone**) in a waterproof housing with cable.

Ideal for building **Arduino** circuits with temperature measurement.

Digital systems operate on the **OneWire** communication bus, which allows multiple sensors to be connected to a single digital pin, such as on an **Arduino** board.

This is possible because each sensor has its own unique serial number.

In addition, the sensors can be connected using two wires in **parasite power mode**.

## Applications of the DS18B20 waterproof temperature sensor

The **DS18B20** waterproof temperature sensor is used for:

- temperature monitoring in cold stores and refrigerators;
- **GMP** monitoring systems;
- monitoring of telecommunications equipment rooms;
- building automation;
- warehouse temperature monitoring;
- environmental monitoring;
- production process temperature monitoring;
- air conditioning monitoring;
- incubation temperature control;
- temperature measurement in culture environments;
- greenhouse temperature monitoring;
- etc.

## DS18B20 sensor features

- Made of high-quality stainless steel.
- The sensor is resistant to moisture, water, and rust.
- Ability to connect signals from multiple sensors to a single digital pin.
- Easy implementation thanks to ready-made libraries.
- All **18B20** digital temperature sensors have unique numbers, and the temperature recording device identifies the corresponding sensor by its number.
