Wall Mount Automatic IR Motion Sensor Light Switch (AC 180~250V)

Pros: big sensitive angle small product comparing to what's found in the stores in my country clear & easy installing diagram i installed it outside at my front door, the sensor detects movement up to 10meters even on an angle of 80degree

Cons: there are 2 turn-switches to adjust the time that the lamp burns and the light intensity it needs to switch on, you can adjust it with a screwdriver the light intensity switch broke of before i managed to get ik to work only chinese manual

Other: very fragile switches, but easy to install sensor, very sensitive and not to big

Pros: Sensibility is perfect. You can adjust the switch-off delay and the light sensitivity. It has a light sensor to avoid switch-on when there's enough light on the room. A delay timer mantains the light on once no movement detected

Cons: The minimum delay timer is 30s, wich makes no sense for home's energy saving option. I'ts slightly big, that forces to hide it in some cases for stetic reasons, but where you hide a device that must see you to turn on the light? ;-D

Other: I've an upper room with the light switch on it, but no on the lower roof, meaning that i must go up in the dark and remember where is the button switch. It solves my problem without passing wire. Very surprised with the light sensor function

Pros: Easy to mount both on the wall or on the ceiling. Easy to mount electrically. When found a correct place and direction, the switching on and off is reliable. Possible to adjust time and light sensor threshold.

Cons: Minimal time delay is 30 sec - ideally should be less for some applications. I have experienced fail switching when the sensor was mounted on ceiling and directed onto floor (probably too strong reflection from the wood flooring). This is solved by partly covering the sensor with a piece of tape.

Other: none

Pros: - Cheap - Works as advertised - Easy to install, took me about 10 minutes per device to get it up and running - Great energy saver, installed 3 of them in places where the lights were often on and nobody there

Cons: - fragile screws to adjust time and turn-on response - manual in Chinese only but thats not a big issue - Getting the wires out of sight is difficult. I Used a smal conduit with adhesive tape.

Other: - Great value for money, just buy it !

Pros: very good sensitivity - it catchs movement from any direction and from long enough distance. the load connected by mechanical relay so it is pretty safe.

Cons: no cons at all - switches on without any delay, switch of delay regulated, the level of light to disable switching on also regulated. everything works as advertised. perfect.

Other: I would recommend it to anybody.
