Temperature sensor DS18B20 1-Wire interface

One Wire temperature sensor

Connectivity Use the "1-Wire" is a serial communications protocol designed by Dallas Semiconductor. 

It is based on a bus, a master and several slaves in one line of data in which they feed. 

Of course, you need a common ground reference for all devices.  

Features: 

1-Wire ® interface. It requires only one port pin for communication. 

Each device has a unique serial code for 64-bits. 

No external components required. 

You can get power from the data line or power supply. 

The operating voltage range is 3.0 V to 5.5 V. 

Measuring temperatures from -55 ° C to +125 ° C (-67 ° F to 257 ° F). 

Accuracy of ± 0.5 ° C -10 ° C to +85 ° C. 

Thermometer resolution is user selectable 9-12 bits.
