The microcontroller reads data from each sensor at fixed time intervals, such as 1 second, and temporarily stores the collected data in the microcontroller's memory. A digital filter is used to filter the sensor data to remove noise, and the data from different sensors are normalized to facilitate subsequent comparison and processing. The microcontroller compares the sensor data with the preset threshold. If a parameter exceeds the threshold range, it is marked as abnormal.
