SparkFun DS18B20 High Temp Waterproof Digital Sensors
SparkFun DS18B20 Waterproof Temp Sensor is a sealed digital temperature probe that measures precise temperatures in wet environments with an easy 1-Wire interface. The probe measures 7mm in diameter and is 26mm long. The overall length, including the wire, is 6ft. The layout interface for the sensor is Red connects to VCC, Black connects to GND, and White to SIG. The DS18B20 calculates temperature in 9-bit to 12-bit configurable readings over a 1-Wire interface. Offering flexibility, the sensor only requires one wire to be connected to a central microprocessor.
