PIR from a BBBW and Python

Hello,

I would be lying to you if I told you I was using this software to test if I was sleeping and moving around while sleeping. But…

This PIR Sensor could be used for this type of testing, e.g. "Did I move while sleeping between a specific interval during the night?"

…

import Adafruit_BBIO.GPIO as GPIO

import time

  

GPIO.setup("P8_12", GPIO.OUT)

PIR_PIN = "P8_8"

GPIO.setup(PIR_PIN, GPIO.IN)

GPIO.add_event_detect(PIR_PIN, GPIO.RISING)

  

while True:

  

   if GPIO.event_detected("P8_8"):

       GPIO.output("P8_12", GPIO.HIGH)

       print("Motion Detected!")

       time.sleep(10)

  

   else:

       GPIO.output("P8_12", GPIO.LOW) 

       print("You are not moving while sleeping!")

       time.sleep(10)

  

This is free software that I use while researching ideas and using an if/else statement.

…

First…assemble the PIR Sensor and the LED.

On your PIR Sensor:

• You have three pins if purchased from Adafruit at
  https://www.adafruit.com/product/189.
• One is GND, another is OUT, and the last one is 5v. These three pins are situated like this to the BBB.
• PIR GND to BBB GND
• PIR OUT to BBB P8_08
• PIR 5v to BBB vdd_5v (this vdd_5v pin needs the 2A power adapter to be plugged in while testing this software)

Now…we need to set up our LED.

• BBB GPIO (P8_12) to Anode of the LED
• Cathode of the LED to 1K ohm resistor to GND on the BBB

Sort of like this idea from Fritzing:

Second…try the source to attempt to make your LED light once the PIR Sensor has detected your movement.

…

If the PIR sensor is not detecting your movement, try to use the 2A adapter like this one:

.

If you want, from what I have learned, you can also use sys_5v on pin P9_7 or P9_8. vdd_5v is P9_5 and P9_6.
