SW420 vibration sensor LOPY4

[Kevis TOMAS]

Hy,

I am trying to make a vibration sensor (SW420) work with the LOPY4 board.

Here is the code currently used in the main file:

import socket
import machine
from machine import Pin
import pycom
import time



def pin_handler(channel):
    channel=1
    print("Detection d'une vibration " ,channel())

pir = Pin("P2", mode=Pin.IN, pull=Pin.PULL_UP)

try:
    pir.callback(Pin.IRQ_RISING, pin_handler)
    while 1:
        # create a LoRa socket
        s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)
        

        # set the LoRaWAN data rate
        s.setsockopt(socket.SOL_LORA, socket.SO_DR, 5)

        # set the LoRaWAN port number for transmitted packets
        s.bind(7)
        #s.send(struct.pack('d', pir()))
        time.sleep(1)
except KeyboardInterrupt:
    print(" STOP")

I would like to analyze the vibration of an equipment to define on-off moments. Ideally, I would like to retrieve the first change in value (from 0 to 1) tell the number of 1 (vibration) in a period (for example 5 seconds) if the number of 1 is greater than 5 for example, I go back to a state (ON or 1).

And the same thing in the other direction, if there is no more operating state for 5 seconds, go back to an end state (OFF or 0).
Do you have any ideas ?

Thanks for your help.
