Hi,
In most of the PIR modules, it is found that a light sensitive sensor is also used, I want to ask what is its function, does it mean that the PIR sensor is disabled when light is on?
Thanks!

Oh I see.
The usual application of such a dual sensor is to switch on the light when someone/something passes in front of the sensor when it is dark. So, yes, during daylight, the PIR sensor doesn't work.
