烧录文件

创建一个.py文件，并拷贝以下代码

#Project 13 - Burglar Detector With Photo Capture
#latest code updates available at: https://github.com/RuiSantosdotme/RaspberryPiProject
#project updates at: https://nostarch.com/RaspberryPiProject

#import the necessary packages
from gpiozero import Button, MotionSensor
from picamera import PiCamera
from time import sleep
from signal import pause

#create objects that refer to a button,
#a motion sensor and the PiCamera
button = Button(2)
pir = MotionSensor(4)
camera = PiCamera()

#start the camera
camera.start_preview()

#image image names
i = 0

#stop the camera when the pushbutton is pressed
def stop_camera():
    camera.stop_preview()
    #exit the program
    exit()

#take photo when motion is detected
def take_photo():
    global i
    i = i + 1
    # 自己选择拍照后要安装的位置
    camera.capture('/home/pi/Desktop/image_%s.jpg' % i)
    print('A photo has been taken')
    sleep(10)

#assign a function that runs when the button is pressed
button.when_pressed = stop_camera
#assign a function that runs when motion is detected
pir.when_motion = take_photo

pause()
