How PIR Sensor Works and How to use PIR motion sensor with Arduino

In this video, we will discuss how the PIR Sensor works and how to use the PIR motion sensor with Arduino with a simple motion detection circuit.

Time Stamps for the PIR motion Sensor module tutorial:
00:48 How PIR module detects motion
01:48 Pinout of the PIR Sensor module & specifications
03:50 How the PIR motion sensor light works
07:14 How to connect PIR Sensor with Arduino
07:32 PIR Sensor Arduino program

After watching the complete video, you can easily use the PIR module to design a motion sensor light or you can also use this motion detection circuit for the security camera or alarm circuit.
I have also explained how to use this PIR module without Arduino. how to adjust the PIR sensor range and delay time.
So this video will give you a complete idea of the PIR sensor module.

Sir I tried and and its working Thankyou for providing This simplest and easy to make but Very good circuit 😍🙂

[cooldata]

Very well explained, thanks for sharing

i have been try to calculate the value of resistance need to use in this circuit and the value is 480 ohm . Correct me if im wrong,
Voltage output sensor = 3.3v TTL
Voltage base emitter = 0.9v for (Vbe sat) Ic = 100mA, Ib = 5mA --> i choose this as the relay will consume aroung 80mA
= 0.7v for (Vbe sat) Ic = 10mA, Ib = 0.5mA
Voltage collector emitter = 0.2v (typical)
As for the formula to find R at base is

R= (V - Vbe) / Ib
R= (3.3 - 0.9) / 0.005
R= 480 ohm

and all circuit diagram i found is using 1k ohm and 220 ohm for bc547 and 2n2222 respectively.

Base on my calculation, if Ib is 5mA then the resistance is 480 ohm, but if i use 1k ohm, doesnt it make it Ib to 2.4mA and Ic around 50mA. That will half the potential of bc547 as it maximum Ic is 100mA. and one more thing is if the amp need to use in relay is 80mA, how can with Ic = 50mA support it.

Thank you sir I have bought the parts in this video I am trying 🙂 I'll reply after making

Great job👍👍💥
How can you connect the PIR to car or motorcycle switch?
Best regards

[gameplayml]

thank you it helps alot
, but can I connect pir sensor to another pir sensor? like when you detect someone the bulb will lights the other pir will lights also, do you get it what I mean?

[MrNams]

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

[Tech_Brigadier]

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

[mr.whitetech]

In My Case it Continues keep Sending The High Signals while All The Connection Are Correct and The Jumper Is Also Placed On Non- repeatable mode. Any solution???

[ramasankarparida]

Can I delay the trigger time more than 5 minute by Arduino.

[borisloncar]

I have a Solar Lamp with a PIR Potion Sensor and a remote control with which I control the light.

tune itni easy circuit ko kitna mushkil bana dia.. sidha sidha ek optocoupler use kr leta hu kitna easy rehta

[jamestheophil]

Can i put the sensor on tree . Bats are destroying the fruits . Can i connect the pir sensor to sound alarm system. Where can i buy this sensor . I have many trees . Bats fly away when sound is emitted. Is this waterproof. It rains a lot here.

[KishorArvindMsBEC]

Will this only detect the motion of a human or can it also detect moving objects that don't emit IR?

are bhai iska high low kihar h. adhe ghante se dance kr rha hu. senstivity and distance high kaise kru.
clockwise ya anti-CW kru
