DS18B20 Temperature sensor

DS18B20 is 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus.

Sensor characteristics:

Sensor type Temperature
Temperature range -55 - 125 °C
Temperature accuracy 0.5 °C
Interface 1-Wire
Working voltage 3 - 5.5 V
