I have installed three sensors in our building for three stairways & compound lightsVery easy to install and working fine.Install the sensor in the place which has lowest light condition in the evening.

Easy to install. sensor switch works accurately.When < 10 lux switch turns onWhen > 40 lux switch turns off.You can measure lux using any sensor app from android playstore.I bought 2 of these light sensor switches for my home. I made the wiring connection according to the sheet provided with the product. Have attached the pictures.The led light in sitout turned on automatically at around 6:30 pm.But there was a small thing to take care: do not place the sensor too close to the led light; at night the led will automatically turn on, but the sensor will receive this light and the switch will turn off and this will repeat in loop endlessly.So to resolve this ( see pics) I placed a cardboard cover for the light to block this light to the sensor. Now the led is constantly on at night as expected.My home do not have street lights nearby so this sensor switch helps to automatically switch on-off lights when I am away.Thank you quicksense.

I have an outdoor street lamp - 40 watt LED - that I keep on at night. I was switching this on and off as required. Fitted the device from Quick Sense and it does the work for me - switching the light on and off at dusk and dawn. Since it is fitted near the lamp and without any cover I am hoping this will not affect it long term.Strongly recomended for any outdoor application.

Initially I purchased only one sensor and take trial for two months with 50 watt load. This sensor found perfectly Working. In my area lights get on at about 7:00 evening and Off at about 6:30 morning.After all testing, we decided to convert all our society external lights on sensors. Now all our LED lights in parking and outdoor lights are on sensor. The sensors are perfectly doing their job. Happy to save the electricity bill.

Very nice, value for money. Two things were missing. One, a black bag mentioned in the instructions. And second a label at the connection points to show the point connecting the live and neutral phase should have been there. However, with help of YouTube connected it, working well.

This device is very sturdy and pleasing in appearance.I have used it in a particular project in which it will turn on/off another devicedepending upon the light from another bulb. Working to my satisfaction for the last one month.Strongly recommend it. I am planning to buy one more in a weeks time.

Installation easy with instructions supplied along with. Wires are of good quality.I have used this relay to control light bulb outside home. It is quite sensitive to direct light. I have covered it with a small cardboard box as my bulb mount doesn't have reflector. Working perfectly. Switches off automatically at around 7am.
