Temperature sensor DS18B20 1-Wire interface
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.
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.
Compatible with Arduino
