This project is about capturing the pictures of strangers through the Pi Camera attached to Raspberry Pi. This is a DIY project which can detect people using the motion sensor(PIR sensor) by capturing a photo whenever the motion is detected.

Hardware

1. Raspberry Pi 2/3/4
2. Pi Camera
3. PIR Sensor
4. Jumpers

Circuit Connection

Connect the PIR sensor to raspberry pi as shown in the above circuit diagram. Additionally connect the Pi Cam to Raspberry Pi camera port. To check whether your camera is working or not run the following code.

raspistill -o Desktop/image.jpg

Apparantly, you should see the image saved on your Desktop, if not make sure you connected the camera properly and restart the device.

The Code

Save the below code as pir-camera-test.py and run.

   #Code for Capturing Strangers:

   from gpiozero import MotionSensor
   from picamera import PiCamera
   import RPi.GPIO as GPIO
   import time

   GPIO.setmode(GPIO.BCM)
   GPIO.setwarnings(False)

   pir=MotionSensor(23)
   camera=PiCamera()
   camera.rotation = 180
   camera.start_preview()

   while True:
    GPIO.setup(24, GPIO.OUT)
    if pir.wait_for_motion():
        GPIO.output(24, GPIO.HIGH)
        #time.sleep(0.1)
        print("Motion Detected")
        camera.capture('/home/pi/Marvel/PiCam/PiImage/Strangers/image-'+ time.ctime()+'.png')
         print("image-"+time.ctime())
         GPIO.output(24, GPIO.LOW)

    else:
        print("Motion not Detected")
    time.sleep(3)
   camera.stop_preview()
   camera.close()
