MAX31825 1-Wire® Temperature Sensor

Analog Devices Inc. MAX31825 1-Wire® Temperature Sensor provides 8-bit to 12-bit Celsius temperature measurements with better than ±1°C accuracy from 0°C to +70°C and ±1.75°C from -45°C to +145°C. The MAX31825 sensor communicates over a 1-wire bus that, by definition, requires only one data line (and ground) for communication with a microcontroller. In addition, the sensor can derive power directly from the data line (parasite power), eliminating the need for an external power supply.
