MMM-PIR-Sensor tuning

[shgmongohh]

@jc21
No with the “original” PIR-Sensor I don´t have this issues. That´s why I it noticed.

I have still the issue with the sensor, that it turns on the monitior at night, when nobody is there. I need a programm to track, how often this at night happens. If it is only one or two times at night or more often.

@shgmongohh Ok I’ll take a look at my stuff soon. I’m in the middle of writing another module that takes a photo when this PIR module senses user presence, if you had a camera attached it might be useful to you to see what the pir is detecting, if anything.

@jc21
Thank you. I don´t have a camera.
I don´t know if the sonsor works not correct or if I have another issue.

When I install your module, have I to delete or uninstall the other pir-module?
I only have renamed the folder.
If i have to delete it, how is it done?

I have found a python programm, where I can track the sensor in a consolen window. Has anybody an idea how i can safe the data into a document? And how I can autostart my python programm?

# Import required Python libraries
import RPi.GPIO as GPIO
import time
import datetime

# Use BCM GPIO references
# instead of physical pin numbers
GPIO.setmode(GPIO.BCM)

# Define GPIO to use on Pi
GPIO_PIR = 23

print "Bewegungsmelder Test (CTRL-C zum Beenden)"
print "========================================="

# Set pin as input
GPIO.setup(GPIO_PIR,GPIO.IN)      # Echo

Current_State  = 0
Previous_State = 0

try:

  print "%s: Sensor initialisieren ..." % datetime.datetime.now()  

  # Loop until PIR output is 0
  while GPIO.input(GPIO_PIR)==1:
    Current_State  = 0    

  print "%s: Fertig! Warte auf Bewegung..."  % datetime.datetime.now()    
    
  # Loop until users quits with CTRL-C
  while True :
   
    # Read PIR state
    Current_State = GPIO.input(GPIO_PIR)
   
    if Current_State==1 and Previous_State==0:
      # PIR is triggered
      print " %s: Bewegung erkannt!" % datetime.datetime.now() 
      # Record previous state
      Previous_State=1
    elif Current_State==0 and Previous_State==1:
      # PIR has returned to ready state
      print " %s: Fertig! Warte auf Bewegung..."  % datetime.datetime.now() 
      Previous_State=0
      
    # Wait for 10 milliseconds
    time.sleep(0.01)      
      
except KeyboardInterrupt:
  print " Exit"
  # Reset GPIO settings
  GPIO.cleanup()

It done. I can tune my PIR-Sensor.
Here is a usefull Link.

Hi, I’very been through a lot of the posts on the White Screen issue, and on this thread. I’m close… I can feel it, but I’ve an uncaught exception that I don’t understand.

link to screengrab.

Anyone offer any tips as to what might be causing this?

I’m on a Pi3 Model B v2.
Have only installed the standard mirror module, and the MMM-PIR module. The mirror is working fine and the PIR module is loading, but the screen isn’t switching off.

@open_book Few things,

1. What version of Raspbian are you using? The onoffnpm module has issues with some releases.
   Hint: cat /etc/os-release
2. What does your config look like for the pir module, exactly?

[open_book]

@jc21
1.
PRETTY_NAME=“Raspbian GNU/Linux 8 (jessie)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“8”
VERSION=“8 (jessie)”
ID=raspbian
ID_LIKE=debian

              {
		module: 'MMM-PIR-Sensor',
		config: {
			sensorPIN: 3,
			powerSaving: true,
			}
		},

@open_book Very strange, it seems the module is trying to activate/deactive the monitor using the Relay, but you haven’t specified a relay to use.

I have noticed however, that sensorPIN of 3 shouldn’t work. This variable is incorrectly named, it is not actually the pin number of the header, but the GPIO number instead. Refer to this Pi 3 image showing which “pins” correspond to “gpio” numbers. You should be using one of 4, 5, 6, 12, 13, 18, 22, 23, 24, 25, 26 or 27.

For example, a sensorPIN of 4 would require the PIR io cable plugged in to pin header 7.

@jc21 hi again, thanks for your input so far.

I’ve had the sensorPIN at 22 previously. And tested it using the python script shared on a few other threads:

´´´python
from gpiozero import MotionSensor
import os

pir= MotionSensor(22)
while True:
if pir.wait_for_motion(timeout=10*60):
print(“It lives”)
else:
os.system(“/opt/vc/bin/tvservice -0”)
´´´
The result spammed “It lives”. Which I understand to mean that the sensor is working… If I change the if to “os.system(”/opt/vc/bin/tvservice -p")" the screen shutsdown.

The reason I changed it was based on the results of “gpio readall”. I currently have power in pin 1 (3.3v), ground in pin 6 and data in pin 15

gpio readall tells me that physical 15 = BCM 22 = GPIO 3 so I decided to try sensorPin: 3.

I’ve changed it back to 22 now, but the result is still the same.

Other possible vectors are:

I’m forcing HDMI output because I’m using a HDMI -> DVI converter and so it seemed like a safe choice.

With dev tools open I can see that USER_PRESENCE is not being logged anywhere in the console.

I followed this post and ran:

“Run npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=49”
in the MMM-PIR-Sensor folder,
