This is a DS18B20 1-Wire digital temperature sensor from Maxim IC (Dallas). It reports degrees C with 9 to 12-bit precision, at temperature range of -55°C to 125°C (±0.5ºC). The sensor uses Dallas 1-Wire protocol and it requires a 4.7Kohm resistor as a pullup from the data to the Vcc line. This protocol allows multiple sensors to be connected on the same bus. Each Dallas 1-Wire sensor has a unique 64-Bit serial number etched into it, so the master can easily recognize each sensor on the bus This sensor is usable with 3.0~5.0V systems.
