3.7 Temperature Sensor

The MCP9808 digital temperature sensor helps the user to measure temperatures between -40°C and +125°C to a digital word with ±0.25°C/±1°C (typical/maximum) accuracy. For more details, refer to the MCP9808 ±0.5°C Maximum Accuracy Digital Temperature Sensor (DS20005095).

The MCP9808 temperature sensor is connected to the WFI32E03PC Module through I2C1 and a GPIO for the user-configurable alert.
