Adafruit MCP9808 High Accuracy I2C Temperature Sensor Breakout

The MCP9808 digital temperature sensor demonstrates exceptional accuracy, delivering a typical precision of ±0.25°C across its operational range from -40°C to +125°C, with a resolution of +0.0625°C. Seamlessly compatible with any microcontroller through standard I2C, its three address jumpers allow connection of up to eight sensors on a single I2C bus without address conflicts.

The sensor is designed to operate within a broad voltage range of 2.7V to 5.5V, making it versatile for different logic levels. Mounted on a breakout board, it includes mounting holes and pull-down resistors on the three address pins for easy assembly. To further facilitate user experience, a comprehensive tutorial and library support Arduino and CircuitPython, allowing for a setup time of 15 minutes or less.

Specifications include: I2C control, adjustable address pins, typical precision of 0.25°C from -40°C to 125°C, a resolution of 0.0625°C, and a typical operating current of 200 μA. The breakout board utilizes the STEMMA QT form factor, featuring connectors compatible with SparkFun Qwiic I2C connectors, enabling solderless connection and compatibility with a variety of sensors and accessories.

Each order comprises a fully assembled and tested PCB breakout and a small header piece, which requires minimal soldering for use with a solderless breadboard. A variety of QT cables are available separately, enhancing connectivity and functionality.
