Where is photocell located?
For most general applications the photocell should be mounted between 6-8 feet of the window area, central to the area illuminated by the electrical lighting that will be controlled. In all cases the photocell must be mounted so that it looks at reflected light only and not at any direct light.
Can you make any outdoor light dusk to dawn?
Hence the name dusk to dawn. These lights can be placed anywhere in and around your garden or driveway. However, unlike traditional outdoor lighting, dusk to dawn lighting doesn't need to be manually turned on or off.

Hook up of photo cell on yard lamp post
Purchased a yard lamp post with a photo cell light activator. The only instruction that came with it was on the plastic bag that said to dispose of due to its hazard to children. Power source coming into the post is 12 - 2 with ground (black wire, white wire, and ground wire. The photo cell has black wire, white wire and red wire.
Comments (15)
Ideally, the photocell itself will be powered 100% of the time. Probably that is the red wire. If you wish the light to be on all the time when it is dark, simply splice the red and black together with the power supply conductor.
What is a photocell for an outdoor light?
Electronic devices that can be used to manage indoor or outdoor lighting are called photocells. The security and safety of your home can be improved by the use of the sensors. When light is not needed, they turn themselves off.
How do you put a photocell on a lamppost?
Use a wire nut to connect the red and black wires from the photocell to the light bulb receptacle. Attach the white wire of the photocell to the white house wire with a wire nut by twisting it.
Can you add a photocell to an outdoor light?
The Photocell is very easy to install, it only has two wires and needs to be connected to the black wire in your light fixture. Attach one photocell wire to the black wire that comes from your house.
Does a photocell need direct sunlight?
I had to move mine to a shaded area because when the lights came on they wouldn’t detect the light.
Step 1: How to Measure Light Using a Photocell
As we've said, a photocell's resistance changes as the face is exposed to more light. When it's dark, the sensor looks like an large resistor up to 10M ohms, as the light level increases, the resistance goes down. This graph indicates approximately the resistance of the sensor at different light levels.
Step 2: Testing and Connecting Your Photocell
Testing your photocell The easiest way to determine how your photocell works is to connect a multimeter in resistance-measurement mode to the two leads and see how the resistance changes when shading the sensor with your hand, turning off lights, etc. Because the resistance changes a lot, an auto-ranging meter works well here.
Step 4: Analog Voltage Read Method
The easiest way to measure a resistive sensor is to connect one end to Power and the other to a pull-down resistor to ground.
Step 5: Simple Demonstration of Use
This sketch will take the analog voltage reading and use that to determine how bright the red LED is. The darker it is, the brighter the LED will be! Remember that the LED has to be connected to a PWM pin for this to work, I use pin 11 in this example. These examples assume you know some basic Arduino programming.
Step 6: Simple Code for Analog Light Measurements
This code doesn't do any calculations, it just prints out what it interprets as the amount of light in a qualitative manner.
Step 7: BONUS! Reading Photocells Without Analog Pins
Because photocells are basically resistors, its possible to use them even if you don't have any analog pins on your microcontroller (or if say you want to connect more than you have analog input pins). The way we do this is by taking advantage of a basic electronic property of resistors and capacitors.
What Is A Photocell Sensor?
A photocell sensor is an electrical device that hooks up and communicates with a transformer. Photocell sensors work like a timer switch in that they power light fixtures off and on automatically during a set “time”.
How Does A Photocell Sensor Work?
With low voltage lighting like with many outdoor landscape lights, photocell sensors tell the transformer to turn on and off based on how much light is present. For example, when the sun sets outside and it starts to get dark, the photocell sensor lets the transformer know that it is time to turn the outdoor light fixture on.
Should I Use Photocell Sensors?
Many people use photocell sensors for energy savings, convenience, and safety. Specifically for outdoor lighting, photocell sensors are a good burglar deterrent because they can power your lighting on and off when you aren’t home. They are a convenience factor since you don’t have to worry about forgetting to turn lights off.
Who Can Install Photocell Sensors?
Licensed electricians like KB Electric LLC should be the professionals to call for a photocell sensor installation. Installing photocell sensors should be left to the experts for proper wiring and safety. Save time and energy by calling an electrician with the knowledge and expertise to get the job done right the first time.
