PIR

[AliciaCrane]

Hi, i am new to Pi and i need some help as a beginner.
I am using a RPi3 and with a PIR Sensor.

So I followed the codes in https://www.raspberrypi.org/learning/pa ... worksheet/

Code: Select all

from gpiozero import MotionSensor

pir = MotionSensor(4)
while True:
if pir.motion_detected:
print("Motion detected!")

and i have connected the same way as the picture in the link but after running, even though there is no motion, lots of
“Motion detected" is printed and it doesn't stop.

Why is that so?? Is my PIR having problem or the connection for RPi3 is different??

Im using the same PIR sensor in this link https://www.raspberrypi.org/learning/pa ... worksheet/
and i connected what is instructed.

However, my sensor does not have the retrigger setting jumper.

There was an almost identical discussion here, from about 2 months ago: viewtopic.php?f=91&t=149724

In that case I think it was concluded that the sensor was faulty.
