i think we are on the same lines however i just need to confirm a few things with regard to the timer i have. A photocell sensor is a photodetector that can sense light. The electrical device functions like a timer because it switches light fixtures on or off automatically. However, it doesn't do these actions using a pre-set time. Instead, it senses natural sunlight to control the switching for the artificial light fixture. Also great for choice for shop window display lighting or advertising systems. IP55 White Photocell Switch for Wall Mounting - Specs the next day the timer will switch on at a time when still daylight thus supplying power to the photocell and when dark enough will activate and turn the lights on A charge-coupled device can be used by the community of scientific because these are very consistent & exact photosensor. When the charge generated by photo-sensitive sensors can be used to examine a variety of things from galaxies to only molecules. 3). Photo Resistor

The issue i have is getting my head around how to wire the timer into this circuit as the manual for the timer is pretty poor and does not explain very well how to wire the unit in. does my brown live wire connect to the live connection of the timer and do i then take another brown live wire from the load? what about the blue neutrals? do these just need to be connected together and not to the timer switch thus bypassing the switch and going straight to the photocell? A photocell sensor is also known as a photoresistor. But it is not like any regular resistor. It is a variable resistor whose resistance changes depending on an external factor (light in this case). And the photoresistor consists of a highly resistant semiconductor material. We are not liable for any loss or damage that may occur through a delay of delivery. This includes failed electrical installation costs.

Please note:

So the conduction band will have more electrons, which makes it easier to carry electric energy and drops the photo cell's resistance. It is possible to measure this change in resistance and use it to drive other electronic components, such as to switch lights on or off.

Passive motion sensors detect the infrared energy emitted by warm objects like human bodies. The movement of these warm objects triggers the sensor to activate the light switch.

Specifically for outdoor lighting, photocell sensors are a good burglar deterrentbecausethey can power your lighting on and off when you aren’t home. They are a convenience factor sinceyou don’t have to worry about forgetting to turn lights off. Because you won’t ever have to forget to turn the lights off, photocell sensors save energy, which saves you money. Indoor lighting with photocell sensors saves energy with the automatic reduction of artificial light.Controlling your home’s lighting automatically saves money and energy. Many people opt for timers to control their exterior and interior lighting. But there is another option: photocell sensors. And the photocell function is adjustable in some units, enabling you to choose the ambient light threshold that will activate the photoelectric switch.

Here are a few things to consider when installing this daylight-sensing switch. Don't Place Then in the Path of Light But photoelectric switches rely on the photocell function, which remains unaffected by daylight saving time. Timers will work on areas within the tropics where the day and night hours remain almost the same. But a photocell will work in all areas because it uses the daylight sensing principle. Photocell Sensors vs. Motion Sensors Plug-in photocells: Work with standard AC wall outlets to control a pass-through plug. They offer a convenient way to turn floor and single table lamps on or off. All damages or shortages will be corrected to your satisfaction as soon as possible with either a replacement part or complete fitting at no cost to you.Switch off the circuit breaker to cut power to the light fixtures. If unsure which one it is, switch all the circuit breakers off. And flip the light switch for these lights to ensure the power is off. The light bulbs should not turn on. Securing and sealing junction boxes makes the installation safe, but it is code-legal to mount the unit higher up towards the roof or ceiling. Also, it looks better that way. Always follow the electrical code. Wrap Up basically the timer will supply the power to the photocell and then at a certain time(lets say midnight) the timer switches off thus cutting power to the photo cell and so turns the lights off Scottish Islands:HS1-9, IV40-51, IV55-56, KA27-28, KW15-17, PA20, PA30, PA32-34, PA41-49, PA60-78, PH42-44, ZE1-3
