Summary
Microchip MCP9808 high-accuracy temperature sensor with I²C interface for precise temperature measurements.
Description
The **Microchip MCP9808 Temperature Sensor** offers ±0.25°C accuracy with user-programmable temperature limits and alert outputs. It features critical temperature alerts, configurable hysteresis, and interrupt modes. The sensor communicates via I²C interface and supports shutdown mode for power saving.
