The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with non-volatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line (?parasite power?), eliminating the need for an external power supply.
Note : You’ll need a pull-up resistor of 4.7K or 10K between the OUT and VCC pins in order for this sensor unit to function properly.
