Simple human body sensor light controller

Overview

Use a transformer to convert 220V to 9V to drive the relay, and then convert it to 5V to power the microcontroller. The main control is STC15W204S microcontroller. The relay is suitable for small-power electrical appliances. The human body sensing and photosensitive modular use switch will automatically count down for 30 minutes and then close the relay after the human body is sensed at night. , turn on the relay, and it will automatically turn off after 2 minutes.

There is an error in the board in the picture. I used jumpers to solder it manually. Now the PCB of the project file has been corrected.

The overall structure is relatively simple, the program is not complicated, and my personal energy is limited. More functions will be added and improved in the future.
