- In this video, we will see how to make an automatic street light circuit using LDR and BC547 on the breadboard. With this simple dark sensor, we can control a 220v light using a relay. During the video, I have shared the complete circuit diagram.
You can replace the 10k resistor with other values to change the sensitivity of the dark sensor.

After watching the video you can easily make the LDR darkness sensor light using BC547 at home to control a 220v light. I have mentioned all the components details in the darkness sensor circuit
Components required for the Dark Sensor
1. BC547 Transistor,
2. LDR
3. 220-ohm Resistor
4. 10k Resistor
5. LED 5mm
6. 1N4007 Diode
7. SPDT Relay 5V
8. AC Bulb 220V
9. 5V DC source or Mobile Charger
10. Breadboard

Not working I make it all correct but light is energized continuously , all components are working well no issue with it but ldr is not functioning with this circuit I don't know y??
same issue
Bahut badhiya bhai maja a Gaya
Your video is very helpful
Love your videos and how simple you make them look. I'm trying to get the pbc Gerber file on your site to order in JPCB.
Thanks for sharing 👍
You are welcome
Supper no words I'm really satisfied☺☺
Thanks
Good video
Thanks
Lovely
please describe how transistor works in circuit.
can i use red LED instead of lamp?
So this is 2 loads connected to collector? One for led and One for Relay?
Yes.
@@TechStudyCell Does it have limit to number of loads that can connect to it?
thank you so much for this my friend
You are welcome
@@TechStudyCell can i ask you a question how about i want to replace the 6v relay to 12v relay what will i do? a big thanks to you in the future
Hello sir I have doubt that if we use 2or 3 bulbs can this circuit works
What if I use 12 V power supply? What all changes would I have to do?
Hello, I would like to ask if i can use a 220-240v light bulb?
We need the capesetar of a fan write
How can I find these transistors and all
इलेक्ट्रॉनिक शाॅप से या आनलाइन अमेज़न से खरीद सकते हैं।
can you put here wiring diagram ?
can i use D400 transistor ?
Can you give a circut diagram for 12v relay without led, what is that diode for
To protect the circuit.
Ye cheezain kaha se milaigee mujhe urgent chahian??? Plz reply???
Bonsoir cool votre projet est il possible d'avoir le schéma électronique de votre projet
way its on directly
How can I email you? Need help with some vintage electronics. Thank you.
You can ask me in the comment section. I will respond.
@@TechStudyCell i bought an unknown power transformer (was told it would be good for this Fender 5F2 tube amp) that I used for my project. I didn't think anything of it at first because all the wires were the same colors as the original Fender diagram/schematics, but after when completing my build, my rectifier tube, 5y3 keeps over heating and burning out. I already went through 2 - 5y3 and afraid to put another in until i figure this out. When I measure the leads: Primary is 120 vac. (i'm from the U.S.), 7 secondary wires: 2 Yellow wires 39 vac, 2 Red wires 93 vac, and 2 Green wires 10 vac. The last wire is 1 red/yellow stripped that I grounded. Now using your formula: Yellow = 3.0v, Red = 1.2v, and Green = 12v. I am trying to figure out the voltage coming out of the power transformer because the vac may be too much for the 5y3 tubes.
