@blebbens said in {HowTo} turn on/off your monitor (Time based, PIR/Button, App):
Thanks for this tutorial…
I am using a PIR. The monitor switches on immediately after detection of motion. I am looking for an option to switch on the monitor if a person stands in front of it for 10 seconds. Mine is a floor mirror, so some people are crossing the floor many times a day without looking at the mirror.
If u use the external PIR script (point 2.2) u could try to change line 25 in the script and define a TURNON-DELAY.
if turned_off and time.time() >= TURNON_DELAY:
The whole script would look like this:
#!/usr/bin/env python
import sys
import time
import RPi.GPIO as io
import subprocess
io.setmode(io.BCM)
SHUTOFF_DELAY = 120 # in seconds, how long the monitor will be on until next button press or PIR detection
TURNON_DELAY = 10
PIR_PIN = 22 # 15 on the board (this needn't to be a PIR. Can be a button also)
LED_PIN = 16 # optional, don't use as Relay-PIN. It just shows detection time of the PIR without delay time
def main():
io.setup(PIR_PIN, io.IN)
io.setup(LED_PIN, io.OUT)
turned_off = False
last_motion_time = time.time()
while True:
if io.input(PIR_PIN):
last_motion_time = time.time()
io.output(LED_PIN, io.LOW)
print ".",
sys.stdout.flush()
if turned_off and time.time() >= TURNON_DELAY:
turned_off = False
turn_on()
else:
if not turned_off and time.time() > (last_motion_time +
SHUTOFF_DELAY):
turned_off = True
turn_off()
if not turned_off and time.time() > (last_motion_time + 1):
io.output(LED_PIN, io.HIGH)
time.sleep(.1)
def turn_on():
subprocess.call("sh /home/pi/monitor_on.sh", shell=True)
def turn_off():
subprocess.call("sh /home/pi/monitor_off.sh", shell=True)
if __name__ == '__main__':
try:
main()
except KeyboardInterrupt:
io.cleanup()
Don’t know if it will work. Just brainstorming cause i haven’t much time
adding modules
