Adjustable Infrared IR Body Motion Sensor Switch Automatic Module Wall Mount Control Light

Works perfect - in our case to switch the laundry room light on and off automatically. Seems to be a good product for such a purpose and good value.Why only 4 stars?Instructions are not in English, so had to figure out the controls by trial and error. They are, looking at the switch from the back, with controls/connections at the bottom, listed from left to right:1> Line2> Delay setting (minimum is fully clockwise)3> Sensitivity setting (maximum is fully clockwise)4> lineWith this I was easily able to set the delay to about 1.5 minutes, with max sensitivity and it works perfectly.I made a diagram but unable to see how to upload here, if possible?

This switch require a common terminal to operate. Without the common terminal it cannot be connected as a stand alone switch.

Bought 3 of these sensors 2 of which I opened and neither one worked. To add insult to injury the sensor does not have an earth connection which can potentially be a life saver in event of short circuit. Pity because I have had these motion sensors all over the house and they are great in saving energy and cut down on the electric bill.

Not a single instructional leaflet or diagram inside , the text is in chinese
