- Photocell. A photocell is a resistor that changes resistance depending on the amount of light incident on it. A photocell operates on semiconductor photoconductivity: the energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance
A photocell is a device that is used to detect and measure light. The dusk to dawn photocell sensor switch will switch items such as lights and fans on during the night and off during the day. A photocell sensor can be regarded as a transducer that is used to detect the light intensity.
The way this works is that as the resistance of the photocell decreases, the total resistance of the photocell and the pulldown resistor decreases from over 600KΩ to 10KΩ. That means that the current flowing through both resistors increases which in turn causes the voltage across the fixed 10KΩ resistor to increase.

The video for the contactor wiring . Thanks 🙏 alot
Xo amazing bro yo da best
Bro nice explanation I keep looking forward to learn more about this
The sound is clear
you are loud and clear sir
I like it
Thax a lot ..i didn't have any idea it was this easy
Just what I needed 3 years later. I see the 🇰🇪 arm band
Thanks I have learn something
good
I like it bro its my dream to learn more and become an engineer
Well understood
Thanks alot bro
What of if the lump has earth wire where will it be fixed?I have noteced that you used to wires from the bulb
Nice Video..well explained
Thank you 🙂
Nice one sir...make some for me about 2,3,4- way bulb switches
I will
You said you will put a link regarding the wiring of the contactor but i cant see it would you please put me through?
Let me update it ASAP
It's nice explanation but i see, why did it go on when there was already light and it failed to turn off as if you have switched off using the switch
Great video bro,you can make another one photocell with contactor?
Yes, soon
Good job, next time go straight to the installation.
I did this very connection for tronic photocell but it kept on , it refused to go off yet it was during day time
How many light 💡 bulbs can be connect into one sensor
@Emmanuel
That sensor is 20A, so you must know the total load current before you connect.
But also you can take advantage of contactor.
Your sensor can control the contactor,then the load to contactor. Op that helps.
@@electreca1 thanks Man
