MCP9808 High Accuracy I2C Temperature Sensor Breakout Board

Introducing the highly accurate and precise I2C digital temperature sensor, perfect for a variety of projects requiring reliable temperature readings. This sensor provides a typical accuracy of ±0.25°C across its -40°C to +125°C temperature range, with a resolution of 0.0625°C. Whether you're using it with an Arduino, Raspberry Pi, or any microcontroller with I2C capability, this sensor makes temperature measurements easy and precise.

With three address pins, you can connect up to 8 sensors to a single I2C bus without any address conflicts, making it ideal for applications where multiple temperature readings are needed. It operates within a wide voltage range of 2.7V to 5.5V, allowing for compatibility with a broad range of logic levels.

This sensor is mounted on a breakout board PCB, which includes mounting holes and pull-down resistors for the address pins, making it simple to integrate into your project. We’ve also provided a tutorial and library for easy setup with Arduino or CircuitPython, so you'll be up and running in 15 minutes or less.
