Review on Sensky BS011 12v 24v DC 3A Automatic Cabinet Sensor Switch with IR Sensor for Low Voltage LED Cabinet Light, Strip Light, and Rigid Light Bar by Instructor Niederhaus

Works great. The trick to turning it on when you open a door or drawer is to place it very close to the edge of the door. Thus, the sensor (located opposite the wires) only "sees" the open or closed door and acts accordingly. If you place it in a place where it has a wide viewing angle, it will react to movements immediately. This may be helpful to some, but since I use it to turn on lights in closets, I mount them on the edge of the door so they don't get in the way. Perfect for Chinese LED strips and with high quality 3M velcro for holding.
