Code

PIR.pyPython
Create new python file PIR.py and enter the following code.
To run the code, open the terminal and go to the directory where your PIR.py is located. Then enter the command " sudo python PIR.py " and hit enter
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

GPIO.setup(23, GPIO.IN) #PIR
GPIO.setup(24, GPIO.OUT) #BUzzer

try:
    time.sleep(2) # to stabilize sensor
    while True:
        if GPIO.input(23):
            GPIO.output(24, True)
            time.sleep(0.5) #Buzzer turns on for 0.5 sec
            GPIO.output(24, False)
            print("Motion Detected...")
            time.sleep(5) #to avoid multiple detection
        time.sleep(0.1) #loop delay, should be less than detection delay

except:
    GPIO.cleanup()
