How to make automatic street light | bt136 | bd139 

Thanks for your reference, please check my another video for this circuit with relay.

I think you mean hysteris [spelling?

You can replace the 220k resistor with 100k and overlap it with a 500k potentiometer to adust sensitivity so partial darkness will not trigger it.

Fake hai...

You should seperate ldr from light

Can I replace BT 136 with other elements as I don't have it?

No

Yes heat sink lagana jaruri hai or bulb 15 se 100w tak koi bhi laga lo.

@@Erpankaj925 thank you so much bhai

@@Erpankaj925 bhai, street light circuit work kar raha hai , but zero ka bulb ( 15 watt ) 50 % brightness kam hua. please tell me bhai

Bt 136 triac hold maximum 4A current and 600v, you don't need to do any modification for using more than 100w bulb. You can use.

Traic BT136 allow 4A and 6A for short time, however when u need more current you may use other TRAIC which are available from 4A-80A

not work

For low Watt lamp 20 30 W??

no

Heat sink jaruri hai.

@@Erpankaj925 Good you understand Hindu writing... Greetings from Argentina!!!

It will work but you have to change resistance value accordingly.

@@Erpankaj925 kitna k ohm

Yes you can, but wattage should be same.

@@Erpankaj925 that's mean the register remain same

Yes

@@Erpankaj925 thank you and last question can you tell how can i give the same voltage ?

Hi sit Can I use heavy duty 220v relay instead of bulb I want to use it for 100+ street light by the use of heavy duty relay contact.please advise. I have used very small LDR but it blasted. What rating ldr do I need?

Less than 50 rs

But single registor not available in online and single piece ldr price is more that is too around rs60

@@mrinmayrayya1199 why you checking online go offline this Ldr is about 3 rs

Sir kaise banayenge

jaise video mai bataya hai

Little bit, but you can place heat sink.

If you want to make it opposite than you watch this video. In this circuit you only need to change relay connection to n/o. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KD2t7azyRBM.html

@@Erpankaj925 thank you but that seems a bit complicated. Is there any way to utilize the BT136 in a simple way like this?

No. You cant change ldr working.

Video me konsa hai?

@@Erpankaj925 sorry dekha ni tha

Maximum kitny watt ka chal sakta ha bulb is pr 100 watt ya is se kam

@@Shorts_lover12 9 to 100 watt

Sir ji bulb blink kr raha ha kia waja ha working tw perfect ho raha ha pr blink kr raha ha bulb

Este es un circuito simple de 3 componentes, no es necesario un diagrama para comprenderlo. gracias por tus comentarios.

5mm

if you give it proper cooling and heat sink than it will last as much other electronic components.

No

@@Erpankaj925 धन्यवाद sir..... respones के लिए

Ldr ko seperate karo bulb ki light se flicker hoga

Same yahi problem ho rahi hai mere sath bhi blink kyu kar ra hai

@@Sunny_sahu_shanky there is another video in my channel for stable circuit which have more components please watch that.

1/4 w

Please send me video in instagram.

3mm use karo

Use 100watt bulb.

@@Erpankaj925 I want for 0.5w bulb can u help me

Try variable resistance insted of resistance and adjust according load.

@@Erpankaj925 12 led bulb how much residents

English please.

@@Erpankaj925 I did it bro, but the led bulb is flickering, what should I do?

There is another video for stable version of this circuit. Check that video.

@@Erpankaj925 video link please ?

Go learn some basic english first.

What are you saying. I don't understand you.

Kya kam nahi kar raha?

Bulb ko ldr se seperate rakho, ldr par light nahi padni chayea.

बहुत प्रयास किए हॆ लेकिन अप डाउन हो रहा हॆ

Mere channel pe ek or video hai automatic light ki vo dekhlo.

Learn electronic first and then try to make circuit.

i dont know why people saying not working .i make all the circuit in front off everyone and tested.

@@Erpankaj925 oh dear..... well first LDRs vary a LOT in value and response which your design FAILED to address. Second the construction is TERRIBLE. Third is no explanation or advice. Just because yours seems to work does NOT mean it is a good design or will work. for others It is a fluke I feel that in trying to use as few parts as possibel / as simple as a design as possible you are ending up with a bad design. I will look for a simple circuit as well - it is NOT easy - but I do not sacifrice things like reliability and robustness

Saman ke saath knowledge bhi honi jaruri hai

what is fake here. can you mention ?

only supported tungsten buld

@@Erpankaj925 led light k liye hum kya use karo

50 or 100 w led light

Do you have experience in electronic project's
