Sensky Photocell Sensor Switch Dusk to Dawn, Outdoor IP65 Waterproof Timer Sensor Switch, LUX and Time Adjustable, Automatic Photocell Switch for Lamps(AC220-240V)

Utilised this sensor to turn on an additional outside light, which was too difficult to connect up to the other circuitry. I found the wiring connections & instructions to be very straightforward. There are little arrows above the connections to clearly show live & neutral in & out. I installed it about a month back, & thus far it is working well without any issues.

Only downside is when power cut it defaults to start the timer from start.Not a major issue in my case.Works well

I purchased this item to operate some new driveway lights. I did not want the lights to operate dusk to dawn & stay on through the night as this is not very eco-friendly so I purchased this item so the lights can be set to come on at dusk, stay on for a few hours & then go off during the night. very easy to set up & works like a dream. Simple connection of power to Sensky & Sensky to lighting ring. Set dusk setting & number of hours to remain on. I really like the simplicity of this unit. You need to remove the screws & open the unit to set it up but that's not a big issue to me personally.

This is a great unit at the price, installed it yesterday and it does the job well. As some have said, the instructions are not elaborate, but there is not much to do, connect wires from the power and wires from the( load) fixture, the earths are just joined together, no terminal for them, be sure to insulate them with electric tape or whatever. Some have said they needed to take it apart to get the wires in. Not so, but you do need a very small Phillips head screw driver to open and close the terminals.

product failed after three weeks was not able to return i would not buy again,

This switch is very easy to install..works well ..Good level of adjustment..looks to be well built with good weatherproofingJust what I needed to controll outdoor lights automatically

For the first five months all worked as advertised but thereafter the lights failed to turn on as programmed at dusk. So it looks as though it will last one winter!

A very useful device, used for switching on lights for a pre determined time at dusk. The item appears to be well made and is simple to set up and use. The down side is that the instruction manual is in 'pidgin english' and does'nt make much sense. The wiring connections are very difficult yo get at , i found that soldering multi-strand copper wire made it much easier to connect the wires into the terminals. Despite the poor manual, the connections are very straight forward. When power is applied and after a few operations of what sounds like an internal relay, a LED flashes to show how many hours the unit "stays on" for following the photo cell "switch on" - a nice feature.
