How To Make A Motion Sensing Light Using PIR Sensor

[@UBsLab]

Thank You for this video. What other transistors can we use ? IRfZ44n? Bc547? 2n2222?

[@ABID5]

Each of these will work

[@UBsLab]

@@ABID5Thanks but which one will have the highest current

[@ABID5]

IRFZ44n

[@UBsLab]

@@ABID5 Ok Thanks, but it won't work on 3.7v lithium battery will it?

[@ABID5]

No it wont

[@dsdhanasekar007]

Hi.how to make it 2 modes. 1, auto turn on with low brightness in evening times & 2, full bright when motion detected ?

[@Лександрик]

Hello, can I use 12V power supply and led strip 3528 about 1-2 meters in this project ?

[@ABID5]

Yes.The same way.

[@parahomi]

Where do I find the 2 1w LED and the 220v to 7.5v power supply as shown in the video?

[@ABID5]

aliexpress for a few dollar

[@parahomi]

@@ABID5 Thank you. Is it possible to use a AC/DC 220v to 5v, 3.3v/600mA 3w Module?

[@ABID5]

yes..

[@RummanNaser]

Very much video

Hi what is the wattage of 1 k ohm resistor?

[@ABID5]

1/4 watt

[@davinderjit98]

ABID Inc. thanks

[@ajmalmaad4497]

Why did you used the transistor?

[@ABID5]

PIR sensor has only 3.3 volt output which cannot light the LED ,so we use the transistor as a switch.

[@ajmalmaad4497]

@@ABID5 does transistor amplify the voltage?

[@ABID5]

No.Transistor is like a switch to turn on Led.If the current on input ( base emitter) increases the output current also increases.

@@ABID5 sure thanks

[@ItaloLima]

Very Cool !!

[@yashh859]

Bro, can you explain the working mechanism please?

[@ABID5]

www.instructables.com/id/Simple-Motion-Sensor-light/ almost Same principle

[@NikhilKumar0612]

why we use Tip122 ,plz explain

[@ABID5]

the output from the pir sensor is 3.3v and less than 30mA,which can not turn the led on.so we use tip122 npn bipolar transistor as a switch for led.

[@NikhilKumar0612]

ABID Inc. can i use BC547 ( NPN ) transistor

[@ABID5]

I'm not sure.It may get hot. will work if you use some 5mm white leds.

[@alfredanto05]

0:26 can you tell me the name of this thing

[@ABID5]

mobile charger circuit

[@alfredanto05]

@@ABID5 what is the name of the charger, I mean specifications apart from 7.5v

[@ABID5]

just usual cell phone chargers, it can be usb charger of any brand.

but it swithces on and off automatically

[@ABID5]

what power supply you using? how many volts

[@mahdijoy894]

😍😍😍😲😲😲 wow it was was cool

[@ABID5]

thank you.please watch my other videos

что за мосфет у вас?

Здравствуйте, это транзистор NPN

Where we set time

[@ABID5]

Turn one of the yellow knobs

[@n.a4038]

Thanks

[@Dhirenswain77]

Can I replace mains with a 9v battery? If so then is resistor needed with dc?

[@ABID5]

the same setup works also
