How To Make Transformer Less Automatic ON/OFF Light Switch Circuit..Simple Automatic ON/OFF Switch..

Friends in this video I will show you How To Make Transformer Less Automatic ON/OFF Light Switch Circuit...Simple Transformer Less Automatic ON/OFF Light Switch..Friends it is a transformer less power supply circuit,,in this circuit we will not use any transformer but we can easily operate this circuit by 220 volt..Friends the circuit diagram of the automatic on/off light switch circuit is in the video please see the circuit diagram..Friends you can connect any electric light with the circuit...Friends we will use ldr in this circuit to sense the light..if you want more sensitivity then you will have to connect two ldrs with the circuit instead of one ldr..Friends we will use a 12 volt relay in this circuit to on/off the light..Friends when the light will fall on the ldr the relay will remain off and the connected light will also remain off but when the light will not fall on the ldr the relay will be on and the connected light will also on..That mean's the circuit will remain off in the light and will be on in darkness..Friends in this way the circuit will work..So friends if you want to know how to make a transformer less automatic on/off light switch circuit at home then watch the video and follow my instruction...Thanks..

***dada namaste u tube par hazaron u tuber hsi magar jo aap ka batane ka treeqa hai wo ikdam nirala hai ek mamuli sa bhi agar jankar hai to bagaer kisi ki sahayta se aaram se bana sakta hai thanks my dear brother aap great ho

[@santoshkumarthakur1698]

Supper sir 👍👍 👍👍 👍
Thank you so much for clarity informative video.
I really like you...

[@VinodKumar-df8vw]

I done it four times ,three times it worked and burned after a while, fourth time it exploded just after plugged,,,but one thing I appreciated is that your explanation is so good ..

[@GKVVx]

Sir, Thanks for your circuit. I am Happy to say that I have assembled the above circuit and it is working fine. In place of fixed 33k resistor I put 50 k variable resister for adjusting the resistance. What I found is, the light is becoming on at 5 pm itself when the sunlight outside is still active. I fixed the ldr on the parapet wall of my house. It is not delaying even though I increased the resistance to 50K of the variable resistor. I want to increase the time for another 30 minutes or one hour i.e. it should become auto on around 5.30 pm or 6 pm. Please explain how to increase the time of its operation.

[@jpscafe7648]

👍👏Seu projeto é muito bom, mas fica difícil pra quem não fala seu idioma; vc nem mesmo mostra as peças e suas medidas,sem esquemático, é ainda + difícil. Obrigado! Valeu.🇧🇷

[@sathananthans]

It is a useful circuit to those who come home late evening after work. I tried this and it works well. But I see that the transistor become warm (somewhat hot). Do I need to check it again or put a heat sink to the transistor. Please reply.

[@eddyyu7091]

Good project, sir. Simple & easy !

[@Techhelp11]

Thanks my dear friend....

[@dhanushkv0242]

Can I use one ldr instead of two and avoiding 33k resistor plz reply for this sir.

[@shantanukumarsahoo9282]

sir i have used 105j400v capacitor and 470uf 12v capacitor and i have only 10k resistors.. except these i have all things u mentioned . please tell me whether i can use 10k resistors instead of 33k resistors or not? if yes plz tell me how ??

[@ashokjadhav7357]

Thank you very much Good Night.

[@Techhelp11]

Welcome my dear friend...

[@GKVVx]

I assembled the above circuit and it is working perfect. The circuit is with less components and very easy to assemble. I want to know how to adjust it to make the light on when it is about to become dark and not when the out side light is still more.

[@Techhelp11]

Friend you don't have to adjust the circuit...It will work automatically ...
