问题描述
我正在使用 PIR 传感器、Firebase、MITappInvetor 和我的树莓做一个 DIY 警报系统。 但是我在处理 bucles 之类的东西时遇到了麻烦。
我想通过更改 firebase 中的值来使用 MITapp 来打开和关闭警报，但我被困在了可以关闭警报但无法再次打开它的地方，反之亦然。
from gpiozero import MotionSensor,Buzzer
import board
import neopixel
from time import sleep
import pyrebase
import json
config = {
"apiKey": "LOL","authDomain": "LOL","databaseURL": "LOL","projectId": "LOL","storageBucket": "LOL","messagingSenderId": "LOL","appId": "LOL"
}
firebase = pyrebase.initialize_app(config)
db=firebase.database()
pixels = neopixel.NeoPixel(board.D21,1)
pirs = MotionSensor(4)
buzzer = Buzzer(16)
buzzeron = Buzzer(20)
buzzeron.on()
def DET(): #When it detects something it does this.
pixels[0] = (255,0)
print("MOVIMIENTO")
data = "DET"
db.child("ALARM").set(data)
buzzer.beep()
def NODET(): #When it does not detect something it does this.
pixels[0] = (0,255,0)
print("NADA")
data = "NODET"
db.child("ALARM").set(data)
buzzer.off()
check = db.child("SISUFV").child("CHECK").get()
pr = (check.val())
print (pr) #this is for the database value,it can be ON or OFF
on = ('"ON"')
off = ('"OFF"')
while True:
while True:
if pr == off :
sleep(1)
if pr == on :
print('"ON"')
pirs.wait_for_motion()
DET()
pirs.wait_for_no_motion()
NODET()
check = db.child("SISUFV").child("CHECK").get()
pr = (check.val())
print (pr)
if pr == off :
break
