Pyroelectric infrared motion sensor lamp (Public)

Summary: This project utilizes a D204S infrared sensor head, controlled by a BISS0001 main controller, to turn six 5730 LEDs on and off, achieving a human body detection lighting function.

Project overview
and appearance illustration. A combination of square nuts allows for 90-degree wall mounting. The red light indicates low battery . The square nut usage
illustration shows that a copper pillar can be used to elevate the back when 90-degree wall mounting is not required. Battery Precautions (Important): Use polymer batteries, with dimensions less than 63 * 50 mm. I cannot provide a purchase link; these were found elsewhere. Polymer batteries within this size range can be used. (Important) The power supply uses a SY8088AAC switching power supply chip, which is stacked on this board and cannot be purchased elsewhere!! (You can draw your own or use a voltage regulator chip). Do not directly connect a lithium battery to the main controller or infrared sensor. The unstable voltage of the lithium battery will definitely cause the infrared sensor to falsely trigger . The D204S is extremely easy to damage. Minimize soldering time. During soldering, it should be suspended 4mm away from the PCB; otherwise, it is easy to falsely trigger the low battery warning and the power will not disconnect when the main switch is turned off, causing a short circuit. The cost is around 10 RMB, plus the battery (I considered the battery as a find). The sensor and chip are relatively expensive . The LED color temperature can be adjusted. My mother likes white, but I prefer 4000k warm light. The hole size on the board is 1.5mm, and the radius is M3. Note this when purchasing (not important). The 4054 series can also be used for charging. I used it on a previous board; it charged at 3000mA overnight and the sky was already bright... (Not important) The large switch is the main power switch, and the small switch is for selecting the single-time light-on strategy; the headlight icon will remain constantly lit if triggered within n seconds (15 seconds in this solution); the small light icon will definitely turn off after n seconds, and the infrared probe signal will be read again after 1~2 seconds of signal stop.
