Thank you for this project! I wasn't completly sure how I was going to connect the PIR sensor to the ESP32-CAM but now I do. My ESP32-CAM will be arriving in a few days can't wait to try this out!

Eletrónica tuga... Uma raridade! Os meus parabéns pela partilha. Mais houvesse como tu...

This is the worlds cheapest Trailcam !! Thank you.

Thanks I was really helpful!!! Do you have tried to involve a RTC to make a time lapse?

FTP upload now as a Video and you are a hero!

Hello, Rui, Thank you for your educating. Looking at your circuit diagram, I believe that the line shorting the 10k resistor should not be there. Your actual circuit does not have it, and it worked nicely for me without it. I just thought that I'd mention it, although I think everyone must have caught it. Unless I am missing something!

Thank you for the reference. Very well done video! - David G

Hello Rui, really liked your video, congratulations! Do you happen to know how to connect and program instead of the PIR motion sensor, a sonic sensor like the HC-SR04 for example? So it can detect also inorganic objects such as airplanes or vehicles. Please let us know! Thanks!

Hello!!! Is there a way to record video when it detects motion??? For example, 5 minute videos....

Nice project, I will definitely try it. One question, what is the purpose of the transistor? will it work without it?

Great video !

I already test it and everything work well, thank you....

Hello thank you both for everything...... will it be possible to use a ultrasonic sensor by the PIR sensor?

Excellent video! Thank you! I was able to save the jpg to SD, I am enjoying！

Excellent explanation ... Which PIR you have used here??

Great tutorial - thank you for video

is ESP32-CAM can be removed from it's downloader (FTDI 232) after uploading the code? it is working properly?

Thank you so much. No way I could have done this without you. Quick question though...when my PIR sensor has detected motion it won´t stop making photos, even minutes after the movement has stopped. What do I do?

Hello Rui, what about saving video files instead of single fotos ? Obrigado

Nice one

There is a mistake on the schematic. The R2 resistor is short-circuited there, but not on the protoboard figure There, the resistor is between the transistor colector and the GPIO13 (and not short-circuited)

hi there , first of all great video :) it is possible that with the wrong transistor the plant take only one photo? trabsistor that I use is a 2n2222a

Hello! Great video. What about to make similar project with gsm module like sim800 or sim900?

Great work, but I have a question what is the purpose of npn transistor?

hola.... gracias me gusto .....¿Puedo usar el sensor ultrasónico para el sensor pir?

Thank You very much Rui Santos, really awesome. keep it up.

is it possible to use a 555 IC timer(astable mode) as a trigger instead of a PIR?

Thanks !

do you have a code that streams video like the example code in arduino (also with the /capture feature to get still pictures for dash bord apps) and also saves a picture at the sd card when motion is detected?

I really appreciate it !!! but I have a question, esp23 cam when I turn on it takes a photo without detecting any motion. every time when I power up it will capture a photo and after taking the first image it will work normally. I want the cam to take an image only when there is motion.

UPDATE: The schematic in the video has a small mistake, view the correct circuit here: randomnerdtutorials.com/wp-content/uploads/2019/08/ESP32-CAM-PIR-motion-sensor-fixed.png Fnd the complete project details (fixed schematics + source code) ► RandomNerdTutorials.com/esp32-cam-pir-motion-detector-photo-capture/ Buy the ESP32-CAM for less than $9 ► makeradvisor.com/tools/esp32-cam/

Thank you for your work/tutorials. I cant upload the sketch while I'm powering with 5V. I am able to upload the sketch without any problems if I'm powering the board with 3.3V. After the sketch it's uploaded the camera would not work with 3.3V, but it's working fine with 5V. Summary, upload the sketch with 3.3V and run the camera with 5V.

How important is the transistor? What is it's function?

... Do you have an updated version of this project that emails the pictures?

Is it possible to install IR leds to improve the photo at night?

Nice, thank you for sharing. I have a couple of observations. 1. When I activate the PIR, I get 3 and sometimes 4 emails with a picture. I looked back at the sketch, the circuit is supposed to send one email each time a presence is detected, then wait for 10 seconds to allow the PIR to settle. I am not sure what the trigger period of my PIR is, which, if too short, would lead me to think that I am getting multiple triggers. If not, what else is happening? 2. I noticed that when the camera is on, my computer (a notebook) loses connection with the internet router. I can still connect to the same router using my iPhone, but not with my computer. I cut the power to the ESP32 board (camera off) and I got my router connection back. Can you please, give me your thoughts on these two points?

Not sure why but I could not get this to run on 3.3v at all. I had to power the ESP-32 CAM from the 5v source as well as the PIR sensor.

Hi Rui, I have learnt a lot from your lessons and have bought few lessons too. As I am an Instrumentation Engineer I was able to make one IoT product which I want to put in Market as a product. I want to know can I rely on Wemos boards or there any high quality and high performance esp8266 boards that I need to use for making that IoT products and selling to customers. Kindly reply in this regard. My best wishes for you always.

Hello Rui, Thanks a lot for sharing such a fantastic tutorial. Do you have any idea on how to retrieve the photo being captured remotely instead of taking it in and out the SD card.

Why does the pir sensor not connect directly to the ESP input pin? The supply range of the pir is very versatile (from 2.7V)

Thanks, great video! Does it work in the dark? (does the front panel LED works as flash?) It seems to me, that it only use the LED if it uses the SD card. Thank you!

thanx genius

Nice tutorial! But I actually ran into a problem. It does not flash when something moves and weirldy there is no 3.3V on the 3.3V pin. Im kinda confused now where to look for the solution...

Hello Rui, what will be the schematic diagram if i use arduino uno instead of ftdi board? hope this comment will be noticed by you. Thanks

Is there a way to compare images to detect motion? If so pir would be not necessary

This a very cool

that's what I was looking for! but I'm going to use a microwave motion sensor RCWL-0516

Can I use any USB to TTL programmer for ESP32-CAM or only FTDI programmer ??

so what is the distance between the sensor and the subject to trigger the photo

I would love to have some WiFi cameras with IR lights and PIR set up around my camp site when I am camping so I can check it from my smartphone. Can you control a gimbal/servos from the board? Any suggestions on building one? We have a lot of bears and bastards around here :( Can you hook one up to a companion Arduino to expand its possibilities?

can the esp 32 camera be connected to an atmeg328p?

Would be better to get a notification on smartphone and the picture. Like with 'Blynk' ord similar. Still nice video

Ola, sou do Brasil e me chamo Ailton. Achei muito interessante este projeto, muito bom. Gostaria de saber como posso enviar estes arquivos para a nuvem (cloud), ou seja enviar assim que tirar a foto.E possivel e como fazer. Obrigrado.

Quando ouço este sotaque já sei que é português. ;)

Can I use this code with streaming video code ? I mean we need add for this code camera streaming video on web .

Is there any way to add night vision to this project?

Pretty damn cool, and ... would have been both really expensive and nearly impossible to DIY ten years ago, hell, maybe even five years ago ... oh how the time flys ... when you have the correct chips in the correct order ... then somehow if not correct time will not fly rather it will slow down infinitely until ... there is nothing. The simple of nothing. The soothing of nothing.

Is it able to record and store video?

In which module did you did coding can you tell me

How could one add a time and date stamp to the photos? Either in the photo name or on the photo itself?

how to setup camera resolution clean picture catch?

thanks for the wonderful guide but can i ask because i followed everything in your guide it is working but the problem is that it only works 1 time. After taking a picture for the first time thats it, it doesnt take anymore picture if you want to make it take picture again we need to turn it off then on again. What do you think is the problem?

Is that PIR sensor module giving logic output? Damn it has just a capacitor. I tried nearly 3 days for analog PIR sensor to logic output. I used comparator and amplifiers etc. What is model number of PIR sensor module? Any link?

Your drawing shows 5v wire, but your video shows 3v3. Why? Which one is right?

Hello Rui. I think there is a problem with your schematic. R2 is short-circuit. May be connect R2 to 5V?

At 2:54 you show a schematic with a 10k resistor r2 shorted out in the collector , it seems like theres is a mistake ?

I'm struggling to disable the flash led... :(

can we record video from it? if yes, how?

Hi,so we did this project we got major error .i.e. when we did a motion the led blinked but the esp32cam didn't capture the photo .the esp32 cam flash stays on it only blinks when we 1st giv supply plz can you help in any way?

Hello, good, Rui, you could make a tutorial video the same as the one you have done with the motion sensor, do it with a vibration or impact sensor, for when the car is hit, take a series of photographs or videos with a delay, if you do it you will do us a favor to the community of those of us who do not know the program, greetings Pedro Luque, from Córdoba, Spain

Sir Im using esp32 cam... I want to turn on a digital output high when a specific image on a page comes in front of esp32 cam. i have four images and need four digital output respectively Can it do it and how??? Waiting for your positive response

can I use BC547

Can save video instead of photos?

I need add living camera to website , please help to add living camera stream to your code

how to fix continously flash but my pir not sensing any motion

There is an error in the schematic, the top end of R2 should go to Vcc, not shorted to itself as shown in the diagram.

Hi Rui, What a great project. I've been waiting for something like this for a long time! I just want to replace my ip cams at home that I don't really trust. One thing still missing though... Can you save the still images to a network drive rather than on the SD? If so, I can setup Node-RED to monitor the network drive in real time and send the images to my mobile phone over the internet whenever there is any motion detected. It will effectively replace those dodgy ip cams. Hope I hear from you soon! thanks.

Finally! error after error, some errors were just Arduino being fussy. it said my board was not esp32 but 8862, It could not connect with board, It wanted a bracket at the bottom of the code....I turned off the computer, cooked food, visited neighbor, came back and like magic it worked.

In my case my esp32 cam is not going to sleep mode its just clicking pictures continuously... So what should i do

I upload the code then I make the ckt and given supply it's not working.

Bagaimana kalau hasil foto di kirim ke aplikasi telegram ?
