Motion Sensor Light Switch Why Does Motion Sensor Switch Turn Light On Immediately After Switching Off?

Why does motion sensor switch turn light on immediately after switching off? - motion sensor light switch

I installed a motion sensor switch standard. The lights illuminate when the device to go with the switch after its proposal in the amount of time the lights sent. (So far so normal).

BUT ... when the lights go back right (within 2 seconds). This is done continuously, without end.

I:

replaced by a new change, and had the same results.
the tape to the "eye" placed on the market, so that no motion / heat can be detected, and the same results.

Somebody out there has ideas?

* Note: This sensor contains no day / night switch, so the problem can not connect with this.
