Processing data locally
Sensor data is first collected locally by the MCU. In most cases, an MCU processes sensor data locally under the following situations:
- Normal situation: The MCU successfully fetches data from the sensor, or the sensor triggers an event as expected.
- Abnormal situation: The MCU fails to fetch data from the sensor, or the sensor fails to trigger an event. In this case, the most likely causes are sensor initialization failure or hardware malfunction.
To enhance the user experience and quickly indicate the service status, consider using a color-changing LED and a buzzer beep on your IoT device to convey meaningful messages to the user.
