Adafruit MCP9808 High Accuracy I2C Temperature Sensor Breakout
The Adafruit MCP9808 is a high-accuracy digital temperature sensor with ±0.25°C typical accuracy over its −40°C to +125°C range and 0.0625°C resolution. It communicates over standard I2C and runs on 2.7V to 5.5V power and logic, making it compatible with virtually any microcontroller or single-board computer.
With three address jumpers on the back of the breakout, you can connect up to 8 sensors on a single I2C bus without address collisions. The STEMMA QT / Qwiic connectors on both sides allow solderless daisy-chaining for quick prototyping.
Key Features
- High Accuracy – ±0.25°C typical (±0.5°C max from −20°C to +100°C)
- Fine Resolution – 0.0625°C measurement steps
- Wide Operating Range – −40°C to +125°C
- I2C Interface – Simple two-wire digital communication
- Up to 8 on One Bus – Three configurable address jumpers
- Wide Voltage Range – 2.7V to 5.5V power and logic
- Low Power – 200 µA typical operating current
- STEMMA QT / Qwiic Ports – Solderless I2C connections on both sides
Ideal For
- Precision environmental monitoring and data logging
- Multi-point temperature measurement arrays
- Calibration and reference temperature applications
- IoT and weather station projects
