UPDATE: Replaced my PIR-Sensor with a Doppler Microwave Sensor.

jordan1200

Thank you for this awesome solution! I just got mine up and running with MMM-PIR-Sensor. I was wondering if any of you have got this microwave sensor to also work with MMM-NearCompliments? I was thinking since it was also inspired by PIR sensor, I could get it to work, but no luck yet.

hello,
i tried this with the microwave sensor, but im out of ideas. i get wrong positives every minute. (i check every 5 sec).
i added also the ferrite, tried another raspberry, different of these sensors (bought a 5 pack) and placed it in a different room. anyone got any ideas what else i could try?
or maybe similar microwave sensors i could try?

any help would be great, tyvm

Did you try and limit the range as described in beginning of this thread? For me option 2 helped to limit oversensitivity.

@uros76
the range is not the problem. i get positives when nothing is moving near it

@Lipax this sensor is very sensitive and catches any movement 360 around from several meters away. I had same problem… If you don’t dial down the sensitivity-range you will keep getting false positives.

@Lipax try dialing down the sensitivity, it’s probably picking up dust or something small you can’t see.

thanks for the help, but i doubt its some kind of movement since its exactly every minute. i tried a different room and its the same.

@Lipax please don’t submit duplicate posts…

all users with reputation below 2 have their posts reviewed… this eliminates all the porn, advertising and trash posts from the forum.

it just takes time for (me) to get to review the posts…

Can you share your python code? Perhaps there’s something there

Lipax

@sdetweil sry about that

@uros76 i hope thats not the problem

import RPi.GPIO as GPIO
import time
import datetime

switch=11


GPIO.setmode(GPIO.BOARD)
GPIO.setup(switch, GPIO.IN)




try:
    while True:
        if GPIO.input(switch) == 1:
            now = datetime.datetime.now()
            print(now.strftime("%Y-%m-%d %H:%M:%S"), "something")
            
        time.sleep(5)
        
        
except KeyboardInterrupt:
    print("Bye Bye")
finally:
    GPIO.cleanup()

thanks for the help
