Circuit diagram : bit.ly/2yvt4u8
tested over and over. this works perfectly, thank you.
👍
esse pir e muito legal gostei ja fiz 4 sensor de presenca e´10
where did you plug the 12V input LED wire
Thanks good video. Could I hook this up to a 12v horn for an alarm instead of the light ? Would I need anything bigger like the diode or transistor ?
Yes you can, Input voltage for pir is +5V for typical applications. Can range from 4.5V- 12V
@@ElectroRetro Thank you ! Subscribed ! ;)
Nice work👏
Thanks for watching
Hello. This worked great for the LED strip on the stairs. I've had someone message me so they can do the same so thanks for the video and responses. Currently I use a smart plug to tell the strip to only come on at night but if you were to add a light sensor and get rid of the smart plug, how would you wire it?
If you open that white cover on PIR sensor you can see a connection point marked RL, You can solder a LDR (Light Dependent Resistor) on that to sense motion only at night time.
@@ElectroRetro Wow it's that easy!? Very helpful thank you.
👍🏼
I have relay modules instead of the stand alone relay. Can I make this work?
Yes
Is it safe to use the diode and bc547 with ordinary 220 volt ? Please answer quickly I am doing it right now
Bc547 and pir sensor must be powered with 5v. You can connect 220v to the relay contact pins.
Can this be used for a 5v led strip?
Yes
Hi...Electro Retro .. really great work 👏👏 can I have circuit with out any relay ..I need simple Hi 9v battery with 4 led PCB design PDF. Ready to itch
You can simply replace the diode and relay with leds
Red brown wire kis chiz ke hai please reply
Red is positive 5v and brown is negative
How about IR sensor
Can I use this circuit in direct sunlight. Will it work or it gives an malfunction…???
Maybe it Will work but sometimes have a false trigger
Im trying to connect a 5V DC motor instead of the relay,
Yes you can connect it
hello sir did u connect the brown and the red wire to another battery of 5 volts
Yes
thank u sir for the very quick reply i will go for it
@@ElectroRetro and by the way we need to use npn type bc 547 transistor right
Yes, use npn transistor.
It's cool, but what is the light for if this light comes on in daylight? Could you figure light to comes on after dusk ?

@@ElectroRetro awesome, will you sometime load a video, for how you do it , thanks 🥰♥️👍👍👍
Yeah.
Can i use this for tubelight?
Yes
@@ElectroRetro hi, if i want to keep the light always on then can i add an on/off switch as well?
You can use a two way switch.
what type of glue u use
I didn't use glue in this video
Hi brother I want to use pir to control my magnetic door lock... Will the same circuit work where the bulb is replaced with the magnetic door lock
Everything is same just replace bulb with lock
@@ElectroRetro thanks for the response will do n share my feedback
Nice. Just two questions: 1) Can I use 12V LED strip 5 meter or long? 2) I want to use two PIR sensor for my automatic stair case light.So how to do that?
Yes, you can use
@@ElectroRetro Thank you. But how to use two PIR Sensors for the stair?
Connect two pir sensors in parallel. Vcc to vcc, signal to signal, gnd to gnd.
@@ElectroRetro Thanks.
Can I feed the sensor with 5v and the LED (5v) also with 5v?
Yes
Hello. I'm using a 12v led with 12v relay. How do I attach the positive and negative 12v to both the led strip and pir sensor? Thanks
Connect supply's positive pin to the relay's common pin and connect led's positive to relay's NO (normally open) pin.
@@ElectroRetro thanks for the rapid response. I shall give it a go.
Hello I'm not getting anything from the led strip. It's only 3 leds but is a 1a supply too low? The relay is rated at 10a. Does the negative of the 12v supply go to gnd on the PIR? I'm basically trying to do your setup but without an additional 5v for the PIR but it's throwing me off completely.
Negative and positive must be connected to the PIR sensor.
@@ElectroRetro hello. Brilliant there is life. There's a clicksound when the motion detector activates. I think it's the relay. Is this normal? Thanks for the help so far BTW, I was ready to give up.
Any way you can show a picture of the whole system, in the video i cant see where the wire are going on the table, battery source
Can you show a circuit diagram with the led on it. I dont know how to make circuit diagram
Just replace relay with a led. And make sure to add a resistor
Hi, nice project, can we use more pir sensors with same circuit (for different angles scan)
Yes, use diode on output pin.
@@ElectroRetro thanks, did i understand right? Vcc and ground pins same connect to 5v input, outputs to diodes on pin, not use another bc547
Example:- drive.google.com/file/d/1fASavSSkePmwn7HxRfWk1D5bIP_22512/view?usp=drivesdk
Everything is same just add diodes on output pins.
@@ElectroRetro thank u so much
This is perfect but i want to use 12v for both pir and led what needs to be changed
Use 12v relay
What about the transistor and diode value? Will it be the same... Thank you for the quick reply. Im not from electronic background so can you please tell me
Same
How to connect a 12V LED strip light directly to the sensor without using any resistor or transistor or a relay. The LED strip light will be powered by 12V 5A driver. The setup will be mounted underneath the kitchen platform. The LED strip light should turn ON when the drawer is opened.
Without transistor or relay not possible.
Is the transistor PNP or NPN?
Npn
can I use 12v Relay
Yes
Sir how should I increase ontime
Adjust left potentiometer clockwise to increase delay.
Can i do this without the relay?
Yes
there is no compulsion like where we need to connect the anode and the cathode of the 1n4007 diode to the relay right ???????????
Diode cathode should be connected to positive.
@@ElectroRetro ok thanx and u didn't need to adjust the distance and time did u ?
You can adjust delay and distance according to your application
@@ElectroRetro ok thanx
Can we use multiple pir sensors in parallel?
Yes you can use
Thanks sir 👍
While the motion detected, relay on multiple times ...giving a continous sound and the light is on ....can give suggestion for thz trouble shoot
Check the voltage on relay coil pins.
The voltage fluctuates
Most likely that's the problem. Check your power supply and connections.
can i use 12v DC?
Use 12v relay
@@ElectroRetro what if a 9v DV BATTERY?
Use 9v relay
can i use 547 to 548 bc
Yes
Can i use BC548
Yes you can
@@ElectroRetro thanks sir
Sir can we use without transistor
New subscriber here
Thank you so much.
Me too. I just subscribed.
sir, I did everything as per this video. but my bulb is always turned ON. I checked my PIR and the voltage is coming properly, my relay is in proper connection (NO)... what are the possible problems?
Adjust you pir sensor delay to minimum.
@@ElectroRetro I kept it brother but still it is the same issue.
You need to check if the voltage on the PIR output switches. Use a multimeter to measure the voltage between OUT and GND.
@@ElectroRetro I did and did not change at all. means it remained the same value.. Should i need to change PIR and check again?
also, NPN or PNP version matters?
Change your pir, make sure you are using npn transistor.
Range?
Upto 7meter
I follow the connection . Why is it. Turning on and off without sensing the sensor?
Please help
When the PIR sensor turned on, it will automatically turn on and turn off after 30 sec.

How to add LDR to this circuit ?
If you open that white cover on PIR sensor you can see a connection point marked RL, You can solder a LDR (Light Dependent Resistor) on that to sense motion only at night time.
@@ElectroRetro thank you ✨️💜️
🤓
Sir, my pir sensor always stays on. What is the problem.
May be your sensor is faulty
What will happen if we don't use transistors
It won't work
can12 v input
5v is recommended

Can you pls tell me in English
Sorry im late
Thanks for watching
can i add 2 motors so that i can make a robot
Yes
@@ElectroRetro and do you have any guidelines for making it
If you are trying to turn on two motors using one pir sensor. Just connect two motors in parallel
@@ElectroRetro okay

Why are transistor and resistor mandatory? What would happen if remove them and connect LED strip light directly?
Reposting as I can't find my previous same comment.
Can't connect 12v load directly to pir sensor. You need a relay or mosfet.
@@ElectroRetro What would happen if neither of these are used and the strip light is directly connected. Will the light get damaged or the sensor? Or nothing will be damaged and the LED won't glow?
@ersomesher There is a good chance for sensor damage.
@@ElectroRetro Thanks for responding. If you have spare sensor and some time, request your kind hello to try that configuration and confirm if it's working or not. I don't have spares, hence the request. Thanks.
As I said earlier it's not possible to directly connect 12v load to pir sensor.
What kind of wire is used?
Hookup wire
Can i use 12v relay?
Yes
