- This device turns lights on automatically when it's a night, and off when it is a daytime, just like street lighting.
How it works: This device turns light bulb ON when it senses darkness and turns the light bulb off when it senses light.
What you need to build this device:
1. MOSFET 2N7000
2. Light dependent resistor LDR07
3. 470k resistor
4. 12V Relay
5. 12V Power Source
6. Wires.

Hi, guys, I put a lot of effort into making good videos, but for some reason only this video got a lot of views, other my videos got unnoticed, so if you like similar projects please check my latest videos as well: ruclips.net/user/ElectricalProvideos
Thanks! Have a nice day.
Can you use photodiode in this project
Change the value of the resistor.
you are the FIRST and ONLY person that has made this make sense after hours and hours of researching how this works!!!
thanks!!!!!
I have been looking for a simple relay switch to ad to a yard light. This is PERFECT and very well explained. Thank you
Simple but Super Project . Gr8 job.
i like this kind of vids. VERY DETAILED
Well explained, thank you and baraka Allah fik
Useful! Good work. :-)
PARABÉNS FICOU MUITO BOM !👏👍
U r using transister LDR resister & rele & this is working excellent work man always made like this video
Thank you for the information, very useful for me
Great vid! How do you fix the feedback light in actual application? Maybe reduce the sensitivity? Or a latch?
nice projekt
Wow excellent experience
i like it thump up and subscribed
MUCHAS GRACIAS Y SALUDOS NAVIDEÑOS DESDE DOMINICANA
Wow! This is awesome.
Tqsm ill make one...
nice project
Very interesting. Thanks
Very good
Nice explain
Hey bud, i want to make this but i have another light dependent resistor the model is LDR Gl5516 can i use it , please reply
Please make lot of amazing video like this video👏
muito bom fiz um pra mim parabens otimo video.
Very Nice Yr Kantt projects
I am sunil
Is there any apparent benefit of using a Mosfet instead of ordinary universal Transistors? Using ordinary transistor need a schmidt Trigger circuitry as well otherwise the Relay chatters when the light is "half bright half dark"
best of the best
nice, thanks
awesome bro thanks
Good idea
supper circuit
And ur video is awesome 🤓
Good and simple
very beautiful
Nice
amazing
video excelente muito bom parabens.
Nice video
nice mama.
Good performance sir
Thank you so much
nice project.
good job
Good job well done..Thank you..i hope if you could do LDR with solar panel & Recharge battery
very good
Great project ! 👏👏Very simple to.build, just a few components 👌
By the way , i thought we need to have a free-wheeling diode connected across the relay, to protect the Mosfet against the back emf
Sir can i use bc548 transistor instead of 2n700? And what kind of resistor can i use if its allowed to use bc548
Hello, you can do a montage if the call does not detect light after a few seconds. It cuts the power of a relay (in 12 volts)
thank you very much
nice bro
wow nice video
Gud idia
a two power source220v for the bulb and 12v for the relay.. thats what i wanted to know,, i am wondering if where can i get a supply from my bulb.. i though that one supply only which can regulate and amplify the current
plz tell me which type and model of the relay you used ?
and also tell me the terminals of each and every tools.
thnx
nice I like this ideal
Easy and simple 😃
Super sir
That was Epic now i can put the lamp in the box and enjoy "Darkness"
@Bok ram Lmao
I think the sensor should be put outside of the house.
NICE
Good
Thank's a lot
nice
Nice project.you should use diode for protec the mosfet
hi there. Can you plz aso suggest an automatic time off and on system for unmanned mobile charging point. so that it does not gets heated off due to continuous charging. It may go off after a specific time and get on after a specific time.
Thank bro good job
can i use 5v relay?
nice...
cool
Can I used in the circuit my hone purpose plzzz tell me
is this posible for 5volts supply?
What will happen if you let the flickering for 12hr? Will the relay melt or Bulb died?
It is realy good thing to you
Tanks for all.
excellent
good
Its really working
v/nice
You might want to put a diode across the solenoid to protect the transistor from back EMF. and also if you include a variable resistor you can adjust the switching point.
I came here to say that 🙂
is there a way to make the opposite thing?
Explain something about Circuit !!!
Nice explained
Thanks!
Hi, if I want to turn off the light at night, turn on at day, how can I do? Thanks
can i do it with dc current?
ooo yea tanks for ur reply
Wow nice it is 100% working now i made it thanks broo
Hello how to make this circuit
I had made this, it's not workink
U made some mistack try gain couse of i done it and its working
Which rating components are used in this circuit? I made it, but light continuesly glown
Good information
please please please upload a video on how to check the resistance of the coil of your relay and how to test the MOSFET... please bro please i relly need to do this. i like the video but it is not working properly. the bulb only gllows on and doesnt turns off when i cover the ldr07.
Kya iska kai matcher transistor agar ho to plz share
It's awesome
i like it thanks
Can we make with 220 AC
Very nice video
I mak projet susesfull
Hello how to make this circuit? I had made this but it's not working
please advice about 470k Resistor (how many watt) i confused in in Ebay and Alibaba.i found many types TNX
In this project, it doesn't really matter. I've used 250 mW resistor just because I like the size, it not small and not too big, so it is perfect for my project.
Hi can I use PN2222 in this circuit
Kya sahi m light atometic on off hoti h or kya ldc ki jagh photo caplar laga sakte h video banaiye sir
THANKS!! IT WORK!! YOU CAN TO USE ALSO TRANSISTOR EQUIVALENT: BC558.
Hi, actually BC558 is not equivalent to 2N7000. To make it work with BC558 you at least need to choose correct value of the resistor, and with a BC558 transistor, you'll also need to reverse the polarity of a power source, because it is PNP transistor.
can i use any npn transistor?
Probably not any, but you can for example try BC547 or similar NPN transistor. I did not test it with NPN transostors at all, so I don't know if it will work, feel free to experiment.
Can I use C828 instead of BC557
Sencar banane maye kiye kiye lagta hai please bataye
XD good
what is the cost of one unit
May I substitute 2N7000 with IRFZ44?
May I substitute LDR with phototransistor?
Greetings from Indonesia
Hi, yes, I think IRFZ44 will work. But, IRFZ44 has a higher "Gate Threshold Voltage" so maybe you will need to replace 470k resistor with something lower, for example with 220k. But I am not sure that it is necessary to replace the resistor... 470k resistor may work just fine.
If you replace LDR with a phototransistor it is not going to work (most likely). LDR is very different from phototransistor, you will need a different circuit for that, so my answer is: no.
P.S. Greetings from Ukraine
thanke you
شكر ا لك
can i use relay in motor parts?
Can you please tell me how to light up multiple light bulbs just by using single LDR sensor?(for light sensor)
If you want to light up multiple light bulbs you need to connect them in parallel, just like in a chandelier. Just google: "parallel connection of bulbs"
