How PIR Sensor Works and How To Use It with Arduino

Wow this is magic

Why is an Arduino necessary? couldn't you just take the output from the pir directly to the relay board input?

Very useful video

do i need a app to work the thing

Very cool! I've been trying to build a remote-controlled relay with camera (Through hardware or on an Android app). Basically, you could remotely connect to the pi / Arduino camera anytime and, hit a button that controls the relays action. Does anyone know of a similar project guide / tutorial? I ask because, I'm struggling trying to build it myself.

great information.

Can you send me the circuit diagram without
bread board

Good day, I am one of your best subscribers and supporter. Would it be ok to ask where can we buy this project?

I was watching for the info on the pir sensor .. amazing breakdown and tutorial! Thank you!

Thank you

I have a Solar Lamp with a PIR Potion Sensor and a remote control with which I control the light. When I press Mod 1 ro on the remote it means that the light will turn on via the PIR sensor. when I get close to the PIR sensor the light turns on and automatically turns off in 20 to 30 seconds. My lamp has a Frenzel lens as you said in the video.

Thanks for the explanation of PIR working

idno pr pis sensor kaise use krien

Can we set the time after which .. the light automatically turn off

Can you use the Pyroelectric sensor for thermal vision?

My repeatable trigger doesn't work. How to fix?

thanks you to vidio

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

thanx

with this work using uno R3 as well?

If wood comes it will detect

Mate, can the same happen using ir reciver led?

What is the maximum range of this sensor?

thank you, and thanks for posting the code

Bro ...ur code is so simple and i was searching lke this....thax.special thax

The sensor can be directly connected to the relay module

Very helpful thank you

Can we put a part instead to the light that can move

Thank you Sir

but sorry it's confusing i'm only 8

well thanks

Sunlight generates IR waves then how it identify humans among that?

Awesome! what is the maximum distance the sensor can detect?

thank you i was looking at changing the sensitivity on mine its exactly what i was looking for, here for an edit i always get motion no matter the settings for delay or sensitivity? not sure why

Looks like "Modjule" for me

The Arduino is really needed at all here? The PIR board doesn't give out a high enough voltage to drive a relay?

Sir i have a question can we detect sun 🌞 rays also with it ?

Brother thankyou

Hi bro

Why does this guy sound like Gru from Despicable Me xD

Can i replace the relay 2-channel module with single one module

Very Nice Video, explained very well..Thanks a lot

good work drog moi

Thanks mate. It really helped with my project :))

How to avoid animals in pir sensor(only human detection purpose)
Any idea ?
Any other sensor?
Please reply

I want it as my bathroom light

posting if anyone is having a problem. code partially worked, lamp turned on and never turned off. i added next piece of code right after first if condition and now it works fine. this way we properly send a signal to the relay.
if (sensorValue == 0) {
digitalWrite(relayInput, HIGH);
}

Good to know this type of motion sensor doesn't emit radiation +1 for well designed technology.

Bro it's not working at all

I follow same steps to make it but it is not working
I also use Arduino mega

But please help

My hc-sr501 gives always high output, what is issue?
