PIR motion sensor HW-416-B does not behave properly. No motion but input is triggered regardless

Question

So, this motion sensor works when it is taped to my desktop computer...but when I move it to the wall, specifically a higher spot on the wall, it just keeps giving back an input signal. So here is a script I am using:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
PIR_PIN = 2
GPIO.setup(PIR_PIN, GPIO.IN)
i = 0
try:
        print("PIR Module Test (CTRL+C to exit)")
        time.sleep(2)
        print("Ready")
        while True:
                if GPIO.input(PIR_PIN):
                        i = i + 1
                        time.sleep(1)
                        print(i)

except KeyboardInterrupt:
        print("Quit")
        GPIO.cleanup()

Simple and straight forward.

This is the output

pi@raspberrypi:~ $ python motion.py
PIR Module Test (CTRL+C to exit)
Ready
1
2
3
4
5
6
7
8
9

and so on. So when I move the location of the sensor in a higher spot in the room, the sensor just keeps going off. I'm trying to understand why.

Answer 1

The code itself is pretty fine. I have just checked, and it looks your issue is very similar the one that described here as the modules are pretty similar. Hence, try to increase your delay before to while loop to 1 min to see if it helps.

For these kind of questions please include a diagram that shows how you connected your sensor module, and a datasheet of the module so we can check specs.
