## Description

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 Package Contents 1× Adafruit MCP9808 Temperature Sensor breakout (with STEMMA QT / Qwiic connectors) 1× Header pin strip Note: STEMMA QT cable not included. Some soldering is required to attach the header strip for breadboard use. Resources MCP9808 Guide with Arduino & CircuitPython (Adafruit Learn) What is STEMMA QT? (Adafruit Learn Guide)
