Human body induction charging night light

Cabinet aisle night light; lithium battery charge management; lithium battery discharge protection; light intensity sensor; pyroelectric human body sensor; LED driver; voltage comparator 

1. It can be charged through an ordinary charging head, and there are instructions.

 2. The switch can control the switch.

 3. When the induction is successful, the light will light up for about 30 seconds. 

4. When it is not bright during the day, no one is not bright.

 5. The position of the iron rod installed on the back is convenient for holding with magnets.

 6. All patch materials can be SMT.

 7. The positive and negative poles of the power supply access part on the base plate are clearly marked; the lithium battery protection IC can be skipped through the pad; the op amp output port is led out through the pin header; the positive and negative poles of the power supply are led out through the pin header;

I bought a batch of high-power LED lamp beads on Taobao. Aluminum substrate, heat dissipation is faster. Due to carelessness, the human body sensing module was packaged incorrectly. Fortunately, I had an ancestral soldering station and successfully removed the sensing module. So the board becomes even uglier. This problem has been corrected in the schematic. Tie the battery and lamp beads together with zip ties. By the way, an iron piece was tied to the back. Yes, it was the three squirrel nut artifact, and now it has become a night light artifact. Add a few more magnets to attach to other metal. It's always dark in the cupboard, and I just need a light that turns on when I open the cupboard. Plate it! The hinges of the cabinet happen to be made of iron and can be held up with magnets. It just blinded my eyes.
