Description

The MCP9808 High Accuracy I²C Temperature Sensor Breakout Board is a precision digital thermometer offering exceptional accuracy and stability for a wide range of applications. Based on the MCP9808 chip from Microchip, it provides temperature readings with a typical accuracy of ±0.25°C and resolution of 0.0625°C, making it perfect for precise thermal monitoring. Supporting I²C communication with adjustable addresses (0x18–0x1F), up to eight sensors can operate simultaneously on a single bus. With its wide supply voltage range (2.7V–5.5V), this breakout is fully compatible with popular platforms like Arduino, Raspberry Pi, and ESP32. The onboard PCB design ensures easy integration, while its low power draw (200μA) makes it suitable for IoT, smart home, and portable applications requiring continuous temperature sensing.
