I have done and I succeed

[@KapilDevMishra]

what is point of inflexion ? lux value at which relay on/off?

[@SheltonManage]

Super Quality Job. Thanks a Lot.

[@user-yg8ww7se7c]

Bro it's very very nice project
Love you ❤️

[@Edmorbus]

Thanks for sharing nice work

[@user-ex7dp7xt2j]

Street light operating system super bro very very usable thanks

[@kavindulakshitha2296]

Great bro👍👌

[@dasarikiran1537]

Hi friend very good job, this is very useful project you are great
TQ Somuch we are expecting in future so many good projects from you in this channel

[@KapilDevMishra]

can we use TRAIC BT136 in place of relay, my load is led bulb of 15W rated at 220V, BT136 allow 4A till 600VAC ? or TRAIC BT136 cause flickering in LED bulb since all LED have some Capacitance (non zero capacitance of LED) ?

[@ynzynz4187]

any suggestion as to where i can buy? if you guys sell it, that would be great..

[@Pilotfly2023]

Tks,friend!

[@unknown_k_chouhan8461]

Can I used bc 547 trangister plz reply 🥺

[@r.pranay4486]

How much maximum ampere and wattage should be for the load?we know the voltage is 230v but what about the amps and watts. Pls reply bro

[@PURRO.]

I have acompetion can i present this plz reply will it work 100prcnt reply me

[@r.pranay4486]

Hii bro can we replace 12v 7a relay with 12v 30amp relay??pls reply bro
It's urgent if you replied Ill be thankful for u...

[@vinayakvn4754]

Great video in TH-cam

[@surya0562]

Agar PCB layout ho to plz reply

[@rpproduction9472]

coming to this project, see you soon @snny hack & science

[@digital_masters_official]

Good job Friend .. ek din Aisa aaega tumhara channel bahut famous hoga .. all the best 👍👍👍😊

[@musicalrainbow5438]

jo abhi nahi hua

[@musicalrainbow5438]

hehehehe

[@surya0562]

PCB layout design nahi kiya?

[@bappuchoudhury6783]

Can I use CBB21 105 J 450 V PF

[@cimacisum]

Saan po connected yung gitna ng trimmer?

[@ghulammohiodin1514]

68k res not finding. Can you guide alternate plz

[@ritaisabel8665]

Good

[@dineshsoni4437]

Brige rectifier kyon nhi lagaaya

[@digital_masters_official]

New video kab aaegi 😉

[@digital_masters_official]

lithium battery power bank . Chargeable 😁😁 new for you

[@PURRO.]

Can u show a clear circuit diagram and is the diagram in ur video same as the project plz reply it's ergent

[@snnyhacksci.5984]

Please see description for the circuit diagram

[@r.pranay4486]

How much maximum ampere and wattage should be for the load?we know the voltage is 230v but what about the amps and watts? Pls tell bro as I have shared ur video to many persons.but all asking about up to how much load is to applied upto how much amps(Max) ?

[@snnyhacksci.5984]

@R.Pranay 448
The maximum load handling capacity depends on the relay you are using; suppose you are using a relay that can handle the maximum load of 10amp @ 230v, then you can use a max 10 amp load and in terms of watt it will be: 10 x 230 = 2300 watt ac.
[ The rating of the relay is usually written on it ]
Note - 1)The rating written on the relay are their maximum value, In practical use, we do not give maximum load to the relay or it may get hot. For a relay rated 10amp@230v use a maximum load of around 7amp i.e. 7 x 230 = 1610 watt. and so on.
2) If you are using a little high current load, then the AC wire or AC path going to or coming out of the relay should be a little thick because this path will be carrying a higher current. In the video, @ 2:12 you can see I am using a little thick wire for this path. also in the circuit diagram, those current-carrying paths are shown bold and thick.
[use wire with a thickness of 0.75 sq. mm or more for this path]
_
_If the same relay as shown in the video is used then you can use a maximum load of 1600 Watt.
Normal LED bulb or outdoor lamp are in a range of 5watt to 300watt which can be easily handled by this circuit.So, you can use almost any lamp available in the market.
Thanks.

@@snnyhacksci.5984 Thank you so much for your wonderful reply. I have never saw any one like u who give the detailed replies.you are awesome.
Do you have any pcb gerber file of this circuit diagram??pls reply bro

[@r.pranay4486]

How much does it works continuously.pls reply

[@snnyhacksci.5984]

It can continuously work for years.
.
[ circuit should be protected from moisture ]

[@user-ex7dp7xt2j]

68k+50k valuable resistance =100k OK sir
