Hi, I am also working a project which is Humanbody speed and direction with PIR. But I want to ask you How can I adjust PIR sensitiviy for human body ? PIR senses all objects heat but I want to PIR sense only HUMAN BODY ? If you answer, I appreciate that. THANKS
My PIR motion sensor lacks the little yellow jumper connecting the repeatable/non repeatable trigger. any tips on how to get around this issue would be appreciated :) Thanks!
Would it be possible to set up four different motion sensors to four different color lights onto the same board? For motion sensing in four different directions. Or would I need to set up four separate projects?
What can I use to measure and compare vibration levels of different cd players ect? Will the Arduino achieve what I am looking for? How do I get a digital readout to be able to read the vibration level and do comparisons between different sources? Just add a multimeter and some cables to the sensor? If I wanted to measure vibration from the chassis of a cd player, do I just place the Arduino sensor on the cd player?
Yes you can do whatever you want... A relay is the best idea to do high voltage and amp stuff. You just need to edit the code so it turns the relay on/off whenever the sensor detects something. It's a simple IF function
Hey what if i wanted to turn this into a baby monitor? For example i'd like to install the sensor in baby's room and the led indicator light in my garage. Is there a way to do this wirelessly instead dragging a long wire from babys room the garage?
hye. how to connect pir, arduino uno and gsm SIM900? is it the gsm need power (electricity) or just need to connect all these hardware using jumpwire only?
Hi, thank you very much. This is really awesome! I am always wondering how do we convert a quadcopter(drone) into a motion sensor drone. Of course there are lot of models available in the market to buy, but can we do that somehow with Arduino or any other sensor devices ?? Please advice ??
Mostly this won't be seen but would that thing turn be able to enable a button to be pressed so say if the sensor wasn't waved the button won't work but when you wave it it will worm
I want to make project something like: There are two door in my room and i want to turn on fan automatically when any no. Of person stay in my room. And turn off automaticall when no one is at room. Can it be made using pir sensor only??
Try covering the sensor with something that blocks IR/heat radiation. Like the silver mylar wrapper of a candy bar. There may be unknown heat sources triggering it.
Hi everybody! It is a common thing, simply the sensor is damaged!!! I had two sensors one is damaged and one is not. Same code working with one and not with the damaged one.
Hi, is this possible to add to a arduino clock somehow? It runs on battery and I would like it to turn off, when no one is in the room and on when there is people in the room
There are two on the sensor itself. Two orange wheels. Those are the potentiometers : One for the time, the other for the distance. Check the sensor's datasheet for more details.
Great work and explanation. This might seem like a beginner question, since I'm a beginner. But can we connect output pin of pir sensor to analog pin rather than digital pin. Thank you.
Could you explain how to wire the same thing as in this tutorial, but if I wanted to have 3 x PIR Sensors? The idea is that if one of the sensors detect movement, the light switches on. Thanks.
Try this: tie three different outputs from the Arduino to one input of a relay. When activated, the relay will turn on the light. Relays are available for 110v and 220v lights. Google: Sonoff
No, there is no "hidden" built-in resistor in pin #13, so you're basically plugging your led between Vcc and ground. It still works because of the internal voltage drop of the led, also pins are limited in current. However, that way you're absorbing more current than necessary (you see the led is very bright), thus shortening the life of the bulb.
Leonardo Lai yeah because those LED’s are incredibly expensive right? No it doesn’t really matter the board does indeed have a built in resistance when plugging in an LED to pin 13 and ground
LEDs' price is absolutely irrelevant here, and I never mentioned it. Of course they're extremely cheap, but why would you want to learn electronics (which is the main purpose of Arduino) the wrong way, just because these components are almost free to replace? Moreover, if you start neglecting the value of resistors (in terms of usefulness, not price), then you are likely to fry a 200$ sensor if ever working on a real-world system. If you get used to best practices since the beginning, your life will be easier later.
The issue i have with the pir sensors is when i throw a large object like a karton box in front of it , it detects movememt. So the PiR works as a motion sensor and not specificly as a PIR SENSOR. How can i change it as s human detector and not as a lifeless karton box detector ? Any ideas?
I have a perimeter alert system I like, but the company is out of business so I cant get more sensors from them. There is a base unit that has 6 channels for up to 6 motion sensors,but I only have one. How can I make a motion sensor from a different security system work with this one, so I can add it to my system?
yea, the program is written like a paragraph and also no setup is placed as serial begin is placed above loop, looks like author not wants to copy the concept, thank you
"You can adjust the time using this potentiometer." Which potentiometer? It might have been informative to show which potentiometer and how to adjust it.
Can you set a delay time for the LED to stays on like a min after PIR sensor detects something? Also can you set the LED to always stay on at 50% brightness until PIR sensor detects then LED is on at 100% Thank you
Hey, I followed your each n every step but my LED is taking more than 2 min to turn OFF after motion detection, can you please suggest a solution on it ??
Shape? That would involve complex math. Position? What about a laser? Point it at a sensor or at a mirror that bounces the light beam to a sensor. Once the beam is broken then you an object is in a particular position. You have probably seen this in a movie or TV show where something needs to be protected such as an art gallery, bank vault, etc. To find out how to use a laser sensor, look for a RUclips video where one is used inside a mail box to sense when mail is present. Then convert how they did it to your needs.
Awesome! I am new to Arduino, and only took a couple of minutes to knock out. Here's a question, is there a way to display the actual time of sensor violation in the serial monitor? Thanks for the information!
Circuit Magic Circuit Magic 1 second ago Yes you can put as many as you want, if more voltage or amp required then use extra power supply with some transistor or mosfet.
Can this code playback a voice message when the led is on ? I need to remind my husband to put the sunscreen (cancer risk) everytime he walks out the door. Please help
You'll have to load a wav file and set a speaker up around the 8ohm range www.amazon.com/gp/product/B0738NLFTG/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
I have the same need. You might want to look at some RUclips videos on using solar to power the system rather than just batteries alone. The solar would charge the batteries. Try this: purchase an inexpensive solar light that is sold for people to place next to sidewalks or driveways. They have a solar cell and a battery. I get mine for US $1 from my local Dollar Tree store. If that works you can always scale up your project to a larger solar array and battery pack.
Thank you sir for your help but can you help me out in my idea of the new project where i want to make my home door to open automatically when someones comes infront of it using the pir sensor and the arduino. If you want to help then sir please send me the code for arduino and the schematic .Thank you.
you can just make it like this: int state; void setup() { pinMode(A0, 0); pinMode(13,1); while(state == 1) { //this while loop is for waiting until pir is calibrated state = digitalRead(A0); delay(1000); } } void loop() { //just put the value of pir as the led state(when pir detects movement the output is high, so the led is high too) state = digitalRead(A0); digitalWrite(13, state); delay(1000); } it's very simple and it works perfectly for me. Otherwise you could use a transistor to switch the led with 10k base resistor. also pin 13 NEEDS a resistor for the led. there is a resistor on pin13 but it's for onboard led and it doesn't effect the output pin.
How can I fix this issue? Sketch uses 2260 bytes (7%) of program storage space. Maximum is 32256 bytes. Global variables use 222 bytes (10%) of dynamic memory, leaving 1826 bytes for local variables. Maximum is 2048 bytes.
Do you have a video that explains the code in a bit of detail? I'm a bit confused by the takeLowTime and lockLow parts on your website.
That was great. Very clear easy to follow video. Nice production quality - good sound and visuals.

Hey
Very nice explanation.
A. Will the pir manage to sense a fly?
B. Is the sensing influenced by surrounding temperature?
Thanks
A. Yes
B. No
Is there any way to get the PIR sensor to send something like a notification to my phone or computer rather than activating an LED?
Sya dtg sbb Mariposa sruh tngk video nih
Just what I was looking for, this is a great tutorial, I will definitely put it to use. Thank you so much!
I completed it and I want my hand to move. What should I use?
THANK YOU FOR SAVING MY NIGHT
Going to add this into my final year project lol! Thank you!
Your college principle is also watching this😬🤐
My hc-sr501 gives always high output, what is issue?
Is it possible to trigger something with more power, instead of a LED?( Maybe something like 5-12 volts.)
Yes. Use a pwm signal to a logic level shifter to drive a high voltage load such as a motor
Brilliant Video! Thanks for helping me... I was in a big need.
My PIR motion sensor lacks the little yellow jumper connecting the repeatable/non repeatable trigger. any tips on how to get around this issue would be appreciated :) Thanks!
Great video, wasn't sure if my PIR was operating, it is!! thanks
Would it be possible to set up four different motion sensors to four different color lights onto the same board?
For motion sensing in four different directions. Or would I need to set up four separate projects?
Is there a way to trigger a speaker output sound effect, rather than an LED light? That would be far more interesting.
Yes, u need to add a buzzer. And do little modifications which is easy and simple
@@vighneshrane6009 can i add the buzzer to the Arduino directly without breadboard?!
@@amerzair858 yes a 5 volt buzzer will work with arduino just like the led connect it to the Uno , or else use relay circuit for 12 volt buzzer

Thank you for giving me knowledge the PIR sensor
Instead of LED, can I turn on 5v battery operated device? Would I need a relay?
Yes you can do whatever you want... A relay is the best idea to do high voltage and amp stuff. You just need to edit the code so it turns the relay on/off whenever the sensor detects something. It's a simple IF function
Are these particular sensors good for outside motion detection lights?
very good quality of explaination

I would highly recommend everyone to wire a 220ohm resistor with the led to prolong the life of the led bulb.
Thanks for your suggestion
Isn't PIN #13 on an Arduino the same as the built-in LED? If so, it might already be protected.
