DS18B20 is a commonly used digital temperature sensor, and its output is digital signal. It has the characteristics of small size, low hardware overhead, strong anti-interference ability and high precision.
Instead of reading a voltage with an analog pin, we read a serial stream of bits from the sensor on one of our digital pins. One such sensor is the Dallas Semiconductor DS18B20. It uses what Dallas Semiconductor calls the OneWire protocol to communicate back and forth between the sensor and the tiny computer. It has three pins, one for power, one for ground, and one for the data link (it is this single data link line that gives the protocol its name).
Feature
1. Digital Signal Output
One Wire interface requires only one port pin for communication. Requires no external components.
2. High Accuracy
Operating temperature range: -55°C to +125°C (-67F to +257F), ±0.5°C accuracy from -10°C to +85°C.
3. Data Line Power Supply
Can be powered from data line. Power supply range is 3.0V to 5.5V.
4. Fast Response
Thermometer resolution is programmable from 9 to 12 bits.
5.Various Probe Design
