# MCP9808 Temperature Sensor Python Library ## Overview Warning: ![](https://cdn-learn.adafruit.com/assets/assets/000/019/778/medium800/temperature_MCP9808.jpg?1411086246) Do you need accurate temperature measurements in a project?  Consider using the [MCP9808 precision temperature sensor](https://www.adafruit.com/product/1782) with up to 0.25 degrees Celsius accuracy!  The MCP9808 will read temperature and make it available over an I2C connection.  With the MCP9808 Python library you can now use the MCP9808 precision temperature sensor with your Raspberry Pi or BeagleBone Black project! Before you get started make sure your Raspberry Pi is running the latest [Raspbian](http://www.raspberrypi.org/downloads/) or [Occidentalis](../../../adafruit-raspberry-pi-educational-linux-distro/occidentalis-v0-dot-2) operating system, and your BeagleBone Black is running the latest [official Debian operating system](http://beagleboard.org/latest-images).  It will also help to familiarize yourself with the MCP9808 sensor by reading its [Arduino guide](../../../adafruit-mcp9808-precision-i2c-temperature-sensor-guide/overview). - [Next Page](https://learn.adafruit.com/mcp9808-temperature-sensor-python-library/hardware.md) ## Featured Products ### MCP9808 High Accuracy I2C Temperature Sensor Breakout Board [MCP9808 High Accuracy I2C Temperature Sensor Breakout Board](https://www.adafruit.com/product/1782) This I2C digital temperature sensor is one of the more accurate/precise we've ever seen, with a typical accuracy of ±0.25°C over the sensor's -40°C to +125°C range and precision of +0.0625°C. They work great with any microcontroller using standard i2c. There are...
