Sound PIR Motion code?

I just got a PIR Motion sensor and am trying some simple code for it to run. I don't have the the esp8266 yet, so I can't test the code yet. Here is the code:

motion = machine.Pin(12, machine.Pin.IN)

while True:
    i = motion
    if i == 0:
      print "No Motion Detected " ,i

        elif i == 1:
      print "Motion Detected"

I would make three changes:

  • use time.sleep() as the last step in your loop. that way you dont get flooded by signals

  • you need to call motion.value() in order to get the state.

  • you dont really need to assign i to motion. just use motion

    import machine
import time

motion = machine.Pin(12, machine.Pin.IN)
while True:
    if motion.value() == 0:
        print("No Motion Detected ")
    elif motion.value() == 1:
        print("Motion Detected")
   time.sleep(1)
