Arduino library for accessing the DS1631, a thermometer which has a precision of up to 12 bits (0.0625°C) and which uses I2C communications. The DS1361A variant differs only in that it starts continuous measurements on power-up or reset while the DS1631 and DS1731 start up in single-shot mode. The DS1631 comes in a small 8-Pin µSOP or SO package and is 3V and 5V tolerant and allows up to 8 devices to be placed on the same I2C bus. The DS1631 datasheet describes the chip in detail.
A detailed description of the library along with further details are available at the GitHub DS1631 Wiki. This includes wiring information and sample sketches that illustrate the library and it's functionality.
