Curious what the tolerances and recommended operating ranges are of these components, in terms of power. If they’ll accept 9v, might they also be able to handle 12v?
I’d like to have a similar system, with a car alarm siren as the buzzer. The siren requires 12v, of course, and I’d rather not fry the circuit between the siren and the power source. Any idea?
*if not, if you don’t hear back from me, it didn’t work.
Can I add 2 or more pir sensor to this same circuit. As I want to be sensed in more locations in house
can you use any bc547? I have tried this circuit and cannot seem to get it working so I assume maybe is the transistor I'm using
Tq s bhai you made my day
सर आपका वीडियो मुझको बहुत प्यारा लगा एक अनाड़ी नया सिखने वाला बड़ी आसानी से सर्किट बना सकता है।
Do you have a link to a store page where I can buy the resistors
Can you use a bc 548 instead?
Bro how can i increase delay time from 3 sec to atleast 30 sec between conservative motion detection ? plz reply thanks
Good and easy. Thanks.
Is the resistor needed on the transistor base? Thanks
Any chance you can link to where one can buy these?
Tx for posting this .is the buzzer activ or pasive?
Can I use a 9 volt motor instead of a buzzer in it?
Can we use 12 v siren in this, and if yes what changes we need to do
Will it work the same way with 6v-12v buzzer
hi,
can you make video how connect buzzers and light bulb led?
how many range required? 2Meters and above
very nice
Bro can you tell me that the transistor is working in as a switch or a amplifiers
Mai bhi aapke जैसा video banata hu
Can I use different led light and buzzer for much higher sound and light?
What led light and buzzer should I use?
hi, Can you pease explain that why do we have to use a 220 OHM resistor from the transistor "B" terminal to PIR out terminal. Please explain. what happen if we don't.
Very nice
My hc-sr501 gives always high output, what is issue?
Can you send pcb layout for this project
What is maximum range?
10 mtr
Is me buzzer kitny volt ka lagy ga
How to make it with AC and siren
Can I get the circuit diagram U used to do this work
What is the range of this sensor
What model of PIR IS THIS???
Friend i got a question it works.
But it works only as a motion sensor and not PIR sensor.
Because when i throw a towel in front of it the alarm Will go off.
I want it to go off only when it detects a large heat source and not lifeless objects like moving curtains etc
I have tried to adjust the sensititvy censor but no luck.
Need.your help to.tackle this
You need to use a HC-SR04 ultrasonic distance sensor for your purpose.
How did u adjust the sensitivity
How much price and from where can I buy it?
Can I have in detailed circuit diagram please
Bro ye kaha par sara saman milega
may l replace the buzzer with a 5v light
Nyc
nice
Hello.. Bro.
Plz reply me....
isme 18650 battery laga sakte he kya. laga sakte he to kaise
Bro 12 volt par par kese kaam karega
How can i connect with 2 motion detectors with only one Buzzer?
Sir,how to increase 20 metres distance and sound
What is the Minimum distance of moving object before the alarm sounded?
Ruben Masanguid 12 or 10 m
How to edit the time of buzzer sir?
how to make it on ac supply and using siren
Is ki coding mil skti ha Kiya...
How to make the led stay on until reset?
Whats is the range of pir sensor, and how we can adjust it
Upto 10 meter. Tested by me
Ok
Buzzer kitne volt ka lagana hain.
5v
@@easytechelectronics thank
This curcuit run on 3.7v battery
Can i find the solder board online?
Yes
Its good but i think pir doesn't work well if we place resistor in front of it...try using comparator which takes input nd gives output like in ir...otherwise it will continuously give high low voltage...as pir signal is very weak it just works with input.
Price for this
Arround 200
EASY TECH not really but okay. More like 30€
pin header female 2.54mm or 2.00mm?
Circuit needed
Do you have any idea how long this would run before it stops due to depleting the battery? Thanks
Not very long if it stays in retrigerable mode. I see in the video it has single cycle mode which will save the battery.
Is buzzer 5v or 12v
5v
Nice... Thanks...
Also please let me know :
220 Ohm Register - How many watt
register to be used ( 1watt, 1/2watt or 1/4watt ...)
470 Ohm Register - How many watt
register to be used ( 1watt, 1/2watt or 1/4watt ...)
Buzzer - How many volt buzzer to be used.
Also if I want to use the high power buzzer, then the circuit would be same.
Thanks once again...
Use 1/4 watt
Plz send circuit digram
Not tried yet but I think it does Not work: Transistor needs a positive input at base but you feed it with negative input via 220 Ohm resistor. Other Parts are ok to me.
No,it is really WORK!The middle pin of pir sensor is actually OUTPUT pin which we can assume that as a positive to the base .Don't let that black wire colour trick you hehe 😎
How can i increase sound??
Depends on buzzer. If you use another buzzer you you will get
Connect a megaspeaker to the source of the sound output that is powered by a powerful amplifier. If desired loudness is not reached. Connect heavy duty speakers to the amplifier, and a microphone at the center of output for the megaspeaker. Now the speakers are adding fuel to the expanding sound of the megaspeaker. Creating what we call a "sonic boom". Further increasing how much you can push the sound. The amplifier needs to be connected to a player with eq settings set to "loudness" for max effect. Ps. If you are able to change the alarm tone to a tune that break the db scales in Edison, add echo to scale it. Preferably a screaming elephant testing his SOS scream in colab with an alpha monkey frightened so hard he shits his pants. Also screaming for his life. You have now increased the sound. For increased result, create materials sustainable enough to not break while the alarm can be heard from some distance.
How to principles work
Bro resistor ka (+ '_ )kese pata kare please help
The colour code of your 220 ohm the resistor is not correct
yes it is
Why when i put the 9v battery the buzzer still on
LED delay gheun on hotay Kay falutugiri aahe yrrr
Can I hav a link to all the parts u got there please
Toby.in or electronicomp.com
Lay ou pmese
How to make it with ac supply
Need 220v ac to 9/12 v converter
Work nahi hote
Time delay and sensitivity sehi se set kijiye
@@easytechelectronics please how much can I buy everything
Mom
Don’t work
How do you know
Not working Fake contanat
Built it and it works for me. Maybe you have faulty components or you did it wrong. Works great in my room.
@@KennethNicholson1972 how did you do yours
