PIR Motion Sensor is not working (script and logs included)
August 29, 2024, 13:53
I have a PIR Motion Sensor from the Edukit Camjam 2, and i am experiencing problems, it either doesn't output anything, outputs one signal, outputs another, outputs both, or sometimes doesn't work at all. Does anyone know a fix for that?
here is my script
python
from gpiozero import MotionSensor
import time
pir = MotionSensor(17)
while True:
pir.wait_for_motion()
print("motion")
time.sleep(1)
pir.wait_for_no_motion
print("nomotion")
time.sleep(1)
problem i am occuring:
the console even thought there is no movement says i there is movement or no movement.
Sensor connected correctly?
yes i believe
also ping me when you answer
Believing is not knowing...
Which instructions did you follow?
Do you have a picture of how you connected the sensor?
i followed the instructions from the worksheets of the edukit camjam2.
i do have a picture and will send that to you right now, also i agian request you to ping me once i answer.
im sorry i can't take a picture right now my lamp is not very good and it's dark
i'll send it tommorow
Here your ping...
But don't ping me, I'll look at my mobile phone when I have time!
How about a link to the instructions?
huh
<@655806508449398834> Then the only thing missing is the picture of how you connected it.
By the way, your code does not correspond to the example... Why don't you try the example code first before you change anything.
i have already tried it
since the motion sensor is sending unuseful stuff it won't work
Then maybe he's looking at it the wrong way? But I can't judge that if I don't see it...
yeah i saw a text saying you should probrally enloce it a little because it's radius is kinda high which i tried but it was still printing out the same
i'll get the photo quickly
im not sure if that's good enough tho
tell me if you need a clearer picture
<@655806508449398834> So I can already see 1 reason why this is not working properly.
You don't have a pin header on the Pi, if you connect the plugs and it can happen that no proper contact is made and then it just doesn't work properly.
So it's best to solder on a pin header, then you can plug in the cables and make proper contact.
does breadboard work instead?
since other stuff like leds and buzzers work straight up like that
You may be lucky and it works, but as the plugs are only loose in the holes, any slightest movement can destroy the contact. It would be better to connect a pin header to the Pi, then there will be no problems with poor contact.
does soldering make the transfering of electricity better, right?
cause i once tried the pin headers without soldering and they didn't work at all
Yes, of course it doesn't work well or at all without solder, how else is the current supposed to flow from one component to another without contact?
It can work if you apply pressure so the pin are pressed against the wall of the hole. But it is unreliable!
I often do this when testing.
i need solder paste for soldering and a solder gun, correct?
Solder and soldering iron, yes.
It is best to use solder with lead, which is easier for beginners because it melts faster than lead-free solder. And make sure you use thin solder with thin tips, otherwise it will draw too much heat away and won't melt.
i'll get back at you once i do all that stuff
alright
i got the stuff
but i don't know what to do really
what is rosin flux and do i need it?
watched a few videos
i mean one
but do you have any ideas on what i can practice?
oh wow
i texted that at the same hour 20 days ago i think?
almost at the same minute]
Apply "Rosin flux" to remove oxidations during the soldering
Here you can see the difference with flux and no flux, https://www.youtube.com/watch?v=M2Jf8cebwCs&t=786s
What kind of components do you have for practising?
what do you mean by that?
You want to solder the pin header to the Pi. You want to practise soldering beforehand. So you need components such as cables or LEDs and a circuit board to practise soldering them.
So what components do you have that you can use?
none xd
i guess i'll not practice
Well then, good luck
