Product Description

1-Wire Digital Temperature Sensor for Arduino (DS18B20)

Measure temperatures from -55°C to +125°C with an accuracy of 0.5°C. Maxim's unique 1-wire bus provides bidirectional communication (and even operating power) over a multi-drop bus consisting of just one conductor.

Each device is addressed by means of a unique 64-bit serial number hard-coded at the factory. This sensor is well suited for the Arduino, which has a library for 1-wire communication. Full specifications and the Arduino library are available below:
