User Guide:
The high level time of the output of this product is adjustable, from 2.5 seconds to 1 hour, the output time set by default is 2.5 seconds, and you can change the time by changing a SMD resistor onboard. Please read the resistance value corresponding to the typical delay time. Refer to the relevant form below.

Resistor   Value 1% precision	Delay time   (seconds)
0 （by default)	2.5
51K	6
91K	8
120K	10
180K	17
220K	32
270K	47.5
330K	62.5
360K	122
430K	243
510K	360
560K	480
580K	950
750K	1865
910K	2790
1M	3715

Blocking time, 2 seconds, not adjustable.
It is defined as repeatable trigger and cannot be changed.
The supply voltage of this module is 3.3V to 15V, and the limit voltage is 2.8V to 18V.
Module output timing is: output high level for 2 seconds after power-on, then go low, enter standbystatus. If the delay time is changed, the time when the module outputs a high level after power-on will increase accordingly, which can be understood as
The startup time after entering the normal working state after the electric power will increase.

After installing the photosensitive element, it DOSE NOT work during the day. It only works at night, it does not contain photosensitive components, and works all day （There are no photodiodes on the module,please purchase separately if needed. Recommended: ordinary F3 photodiode )
It is considered that there is no photosensitive element installed.
When soldering with 220V ordinary soldering iron, it is necessary to unplug the power supply before welding. It is recommended to use 24V low voltage soldering iron, such as domestic white light 936.
If you follow the MCU and connect the lamp, please read the reference circuit diagram below.
