Common human body infrared monitoring devices have a relatively simple function and need to be manually set to play a welcome message or a siren sound. In actual use at home, what we need to hear is the welcome message during the day, and the siren alarm sound is only needed after going to bed at night. It is said that there is a need for an intelligent human body infrared monitoring device that can not only automatically determine the monitoring playback content based on the time period (day or late at night), but also automatically record the time when the monitoring is triggered.
The overall idea of the project is to use the GD32E231 development board as the main control unit, use the LCD5110 display screen and two user buttons as the human-computer interaction module, use the infrared probe for monitoring, and use the AT24C02flash chip to save and record the triggering time of the monitoring alarm, so that Initial implementation of basic intelligent functions.
