THE TRANSMITTER RESISTOR WILL BE 100R not 100K.

Brilliantly explained. I have a few of these and some use LM358 and some use LM393 comparators with the same schematic. I can never get them to be accurate past 5cm. Which, for my application, is fine, but not for others.

What is the output voltage of this sensor with respect to ground? Because I want to use its output as clock input of a counter circuit.

Great stuff! Thanks so much.

Hi does minor change in resistor value makes circuit not to work??

very helpful video. I need some help w/ a project where I need to make an IR sensor from scratch with blank pcb. I need to know whwere I connect my power source

You are good teacher but you are not an electronics specialist.

But does it reverse polarity automatically? Like AC signal? What frequency can it switch?

Why would you need all that if you can just reverse 2 wires on dc motor and jave reverse polarity

wouldn't motor voltage be much greater than the "1"? that would mean D1 is reverse biased also.

ily

Ok nice what about the other direction boss? ie 5 to 3.3v conversion

And LEDs ate drawn with arrows pointing out

In your thumbnail picture you show 100k for it, glad you corrected it in video

hello sir after watching your video I thought if I can use a PIR sensor instead of an ultrasonic sensor in obstacle avoiding car will it work or it will keep crasing

Nicely Explained!! Good Job!

This is fake or real

Amazing

The best video on ir sensor module I found, exactly what I was looking for, thank you TechWeek. . .

Thank u very much

Well explained. Did you mention the other direction from 5v?

thanks!

👌👌bro.... very helpful

Can I able to shift 400 milivolt ,-400 milivolt to 1,0 volt by this

Hello, Can I ask question about PIR?

@TechWeek. Could you please be so kind as to tell me the identification code on the IR and LED and photodiode? Thanks mate.

I am 1 k like,😁🌹

Thanks a lot for the video superb explanation.. It used a lot to me in this less time....

Can we connect gate terminal to 5v?? And if it do so what is the output??

For IR LED 100K is much much too big. It should be about 100 Ohms.

Well done

Thank you very much😁

How much long range it can cover broo please reply

Hey .. how does fast motion and slow motion afffects sensor?? Also does the objects' shape and size matters!? Pls reply!!!!!

V clear tq 👍

Well explained!! ♥️♥️

Awesome sir

Nice

What is mcu in working of ultrasonic sensor

I dont understand what you are saying about the trigger pin.

Can do video on working principle & circuit diagram explanation of line follower robot by using IC L293D plzz sir

Well done cool explanation, Thank you.

With the same circuit, can I interface 12v at HV side and 3.3v at LV side. The reason I ask is... I want to interface a npn or pnp photo electric sensor to the stm32

how to connect this

Will the pir sensor works in rain when it's used in outdoor

Very well explained in simple clear layman language. Only calculation of microsecond was a bit confusing could you revisit the page and see. Well done. Keep posting.

can u explain circuit diagram of ultrasonic sensor in anthor video ?

Thank you very much it helped a lot

You explained it wonderfully, however I have Perps using this to create sound and tunes out when you said where I would need to put it to gauge the waves

Thank you
