Introduction: Photo Sensor Controlled Outlet (turns on or Off at Daylight or Nightime)
If you look around, it is very easy to find a photoelectric sensor switches that shuts off lights during the day. What if your project needed you to turn on a item during the day and shut it off at night. I guess those are also readily available but at a ridiculous prices nearing $100+. This kit allows is made up of readily available parts, you may even have them in a parts bin.
I made it using separate GFIs. The reason is simply because they were available. You can save money by getting a GFI electrical cord. Personally I don't mind the double GFI protection. If day time control trips I won't loose my night time control.
- Extension Cord
- Cord Grip
- 1 or 2 GFI Outlets
- Relay Socket
- SPDT 120v Relay
- Photocell or Photoelectric Sensor
- Wire Nuts
- 120v Small Bulbs
- Step Bits or Drill Bits
- Wire Strippers
- Painters Tape
- Knife or Dremel
- Outlet Cover (for template)
This is just for experimental purposes. Project boxes are not UL rated for 120v electrical. If you are interested in making one you can simply replace the project box with the plastic UL rated electrical boxes.
Step 1: Prepping Project Box
Drill out the hole for the electrical cord. Be sure to insert the nut of the cord grip first before you begin wiring anything otherwise you will find yourself having to undo all your wiring in order to slip the nut on. At this point I went ahead and separated the ground out into 2 for each outlet.
Step 2: Creating Labels
I started to create labels for all my wires to make it a breeze when it comes time to connect them. After-which I went ahead and started placing some of the wires where they belong.
Labeling makes for a much easier project build. Below you will see the label list followed by a text diagram of where they go. I labeled them in layman's terms so they are easier to understand.
Also label each outlet (night or day) if you are using two outlets. Disregard if you are just using one.

Prep wires by splicing at each end (approx. 7) and add labels. Here is a text diagram of what labels go on which wires.
--- Dotted lines represent a wire
[ ] Brackets are the Outlets
#7 Relay--------------------White Wire (cord)
#6 Relay--------------------Hot/Black (cord)
#5 Relay--------------------Hot/Black (cord)
[day]-------------------------White Wire (cord)
[night]------------------------White Wire (cord)
Red Wire - attach to #8 on relay
Black Wire- attach to Hot/black wire on supply cord
White Wire- attach to White wire on supply cord
Night Bulb- One wire goes to White wire on supply cord the other goes to #2 Relay
Day Bulb- One wire goes to White wire on supply cord and the other to #3 Relay
Step 3: Prepping Faceplate
I started to create the faceplate for the project box. I taped up the cover with frog tape and put double sided tape on my template (the white outlet cover). The cover turned out to be a great template. I drilled out the corners then began to cut with my olfa knife. It took a few swipes but it worked out fine. I marked my holes for the bulbs and the photoelectric switch. once complete I wired up the face plate. The bulbs must be fed through the faceplate before wiring up.
Step 4: Bulb Wiring
Grab one of each color wire from the bulbs. It doesn't matter which wire. What I did was solder both of them along with another wire that will attach to the white supply wire. I did that because the wires were so little that I felt they would come un-done inside of a wire nut. Espessially when the would be beside a much wider wire.
Step 5: Wiring It Up
If you followed step 2 and created all the labels necessary. I'm sure you also attached all the labels to the appropriate wires. You can now begin to attach all the wires to the appropriate locations.
Please note that I added a jumper from relay number 5 to number 6. You can see in the picture above.
Once you are done you can install the outlets to the faceplate and install the plate. Congratulations you just created your own light controlled outlets.
Step 6: Other Applications
This light control can be created with just a day or night time control. It can also be made in a much smaller manner with both day and night control by using a special outlet that does not have both outlets wired together or better known as an altered dual outlet. No worries they are available at your local hardware store.
