HS23P1820+ digital probe solar triangle wall lamp scheme introductionApplication scheme

Scheme description：

Solar triangle wall lamp is a kind of common pyroelectric human body induction application, the use of solar panels to charge lithium batteries, can detect day and night, daytime standby energy saving, night detection when someone moves automatically light up, can be switched by key machine.

Using HS23P1820 + digital probe to make solar triangle wall lamp scheme, the peripheral device is simple and the programming is simple.

Function description：

Key sequence：OFF →Induction ON/Induction/OFF→ OFF → Cyclic power-on enters OFF by default

The file function：

1、Induction/off: at the beginning, the heat engine is 100% for 15s and then off, and then the induction is started. After that, the induction is 100% delayed for 15s, and the induction refresh time can be repeated. 15S End Off.

2、OFF: turn it OFF Low power standby

Solar light control：

Check the high voltage of the solar pin.When the voltage is low, return to the previous mode
