Ubedljivo najbolji tutorijal koji nadjoh na netu u vezi PIR-a. Hvala najlepse!

I have been using PIR sensor from long time I did not know that repeat and Non-repeat thing. Good one bro.

[Canadazeus]

Excellent tutorial. I finally get to understand how to use something without further research. Thanks.

Thanks a lot for making this tutorial, and making everything clear in just 4 minutes :)

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

crisp yet super informative, good work man!

[ruffnck]

You’re the best at detailed explanations

You can run the sensor directly with relay module or use a transistor in the middle because the sensor board has enough controls for distance and time even giving logic signal as output. However if the application requires processing or running a certain control schema with multiple sensors Arduino will be required. Arduino will take care of all timing and trigerring, only the distance needs to be adjusted at the level of sensor board.

This guy sounds like an extremely smart version of Borat.

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

Good explanation of PIR sensor activated electronic circuits. Thank you !

Excellent know-how on PIR sensor Dejan. It was quite enlightening. Looking at your vast expertise in such devices, I would like you to do us enthusiasts, one more favour.

There is this device "Omron D6T Thermal Sensor", which is also based on sensing the body heat, but better than PIR sensor, as it does not require motion to occur, to get triggered. The advantage is that as long as the human is in the frame of view, it stays triggered, unlike the PIR sensor, where if the human stays at one place without moving, the sensor is not able to sense the human presence.

I have been looking around the internet for some help in using this device, but could not find any proper resource. Would appreciate if you could teach us to implement this device through a suitable project. Your teaching technique is very easy to understand and would definitely help everyone in getting to know this device and using it successfully.

Many Thanks and keep up the good work.

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

[imnotleoz]

omg, thank you so much! I was trying to write a code which will enable the LED to be on as long as there's movement!!! now I'm going to trying the repeatable mode that you just mentioned to see if it really works without changing the code !!

EXCELLENT!
I want to make a motion activated sprinkler to keep deer out of our garden AND wanted see if an Arduino or PI would be of any use in the sprinkler contraption. Your video nailed it. THANK YOU!

[eliasibrahim]

Thank you very much for making such a great tutorial.

[satalajmore]

Thanks for the explanation of PIR working

Dear friend, can I use part of your video in my company on-line seminar? I'm not sure if I can get your reply here, but look forward to your answer.

[ilhamrhomadony]

thank you very much for your tutorial, its so helped

[karenberry]

This is a great tutorial, thank you very much... John :)
