Easy to use with just only a transistor (or other) needed to amplify, buffer the output. Include the control over sensitiveness and time. Very good range and sensitive even at "middle" setting. Even a centimeter of hand movement can be detected at range of 3 meter. Very wide angle of detection, don't need to point directly at target position (also can be a Cons in some situation).
A bit Bigger than I first though (in fact I think it huge! compare to other PIR). Front plastic cover don't have locking mechanic, you need to make it yourself. So, If front cover got lost, you need to replace it or it will probably don't work (which replacement can be hard to find because of the big size, easier to just buy a new PIR).
Very good product and price. I'm not sure if this module alone can drive current-hungry components like motor or relay (I always throw 1 transistor in every sensor-liked component just to be safe).
