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

[@maza6357]

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.

[@cristian-bull]

Depending on the relay module and the sensor, it could not work. Some sensors have a 3.3v output. Besides, the relay in the example is active with a negative input. Anyway, the Arduino can be replaced by a transistor ._.

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

[@imnotleoz5486]

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 !!

[@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

[@ForgottenLegendsOfTomorrow]

what do you mean about non repeatable trigger? can't understand. an example would be helfpul

[@charleslyell3748]

Repeatable trigger: every time the sensor detects a movement, It resets the timer to zero. Otherwise, the timer starts counting after the first detection and posterior detections will be ignored.

[@NBSuperb]

is there any method to reduce the delay time to 0 so we can take continuous inputs?

[@umxrr8677]

Change the jumper to other side

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

[@ColinRichardson]

I presume you could do this without the arduino? Have the out on the sensor connected to the trigger on the relay and change NC/NO for the lamp? Just need a 5v source to power the relay and sensor?

[@krishnakumariyer4579]

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.

[@mfdares1809]

First things first.. great tutorial... well done.. Since there is so much demand for a minimalistic working motion sensor tutorial (without Adreno)... Could you please make one... and share it. While making the tutorial.. MAKE SURE THAT YOU KEEP US IN MIND..... WE KNOW NOTHING ABOUT CIRCUITRY (NOT EVEN Soldering, OMs, resister, etc...). So,I request you to kindly make a real simple tutorial for us....if possible a minimalist one, without resister, OMs and a lot of explanation. Also make sure that you share your tips and tricks And the mistakes you did (so that we don't repeat them). I did search the internet and KZbin.. But couldn't find a tutorial with simple design and instructions. if anyone knows of such tutorial, please share the link. I'm planing to power a 5050 led strip with 12V, 2.5 or 5 mAh battery, Activated by this motion sensor.. If possible please let me know the minimum things required for this project.. ( right now I've got 1.battery, 2. Leds, 3. PIR motion sensor.)

[@aglan]

Is there a way to dim the light for example if PIR sensor detects an object then the light will go ON and keep it on for sometime. Now if there is no object for 20 minutes, instead of turning off the light but dim the light instead for like 30 to 50% instead of 100% ON. Thank you.

[@johnossi4234]

Good tutorial. How do you read out the untriggered real time sensor output?

[@xall1e]

+John Ossi It returns either "motion (1)" or "not any motion (0)". Something like this would do the job :) #define pir A0 #define led 4 void setup() { pinMode(pir, INPUT); pinMode(led, OUTPUT); Serial.begin(9600); } void loop() { int val = digitalRead(pir); digitalWrite(led, digitalRead(pir)); Serial.print(val); Serial.print(' '); delay(100); }

I have a Solar Lamp with a PIR Potion Sensor and a remote control with which I control the light. When I press Mod 1 ro on the remote it means that the light will turn on via the PIR sensor. when I get close to the PIR sensor the light turns on and automatically turns off in 20 to 30 seconds. My lamp has a Frenzel lens as you said in the video.

Whats the difference between PIR and IR from a surveilance camera

[@clientesym]

can the board send an sms when battery its low and when detected movement? can it be set to standby when no movement its detected to save energy?

DO YUO THINK THE RIP SENSOR IS MALFUCTIONING?

[@andrejklochan2286]

The code is incomplete, you have to add: else{ digitalWrite(relayInput, HIGH); }

digitalWrite(7,HIGH); remember relay would turn off when the input is high and turn on when input is low !!! if you need full audrino code for anything then you can contact me !!

May I ask you to give a fact based assessment about using the PIR sensor with either Arduino or a Rasberi Pi. The PIR is basically used in security situations and I seem to find only Rasberri Pi board uniting with PIR and exhanging through GSM WITH sms to cell phone notification

Will it work for an automobile as well ?

[@kpf2875]

It was well explained. but i have a question. i have a pir and i am planning to make a motion sensor and i placed servo motor so it would rotate 180 degrees. but why will the pir detect something even if it is only moving ? i mean there are no humans or animals in front of the sensor, the servo is just moving the pir and the pir will detect something causing my alarms to beep. how will i solve this problem ?

Very cool! I've been trying to build a remote-controlled relay with camera (Through hardware or on an Android app).
