If you read the programming instructions for the PMS02 that I referenced
earlier, it should become clear. On sensing motion, the sensor sends an ON
code to a user programmed address. After a user programmed interval, it
sends an OFF code to the same address. On sensing dawn (or any light) it
sends an OFF code to an address that is one unit code higher than the motion
address and at dusk (or lack of light) it sends an ON to that higher
address. If you place the sensor where it can "see" the lamp controlled by
motion, it will "think" it's dawn when the lamp turns on and dusk when it
turns off, leading to confusion.
