Grove PIR Motion Sensor for Beaglebone Green

Products & Technology Grove
#1

Hi! I’m trying to use the Grove PIR Motion Sensor for my Beaglebone Green and I can’t find any setup information on http://wiki.seeedstudio.com/Grove-PIR_Motion_Sensor/.



How to access the data pin / pin 2 from beaglebone green?

Hi，


  1. please run below commands



    sudo apt-get update

    sudo apt-get install libmraa1 libmraa-dev libmraa-java python-mraa python3-mraa node-mraa mraa-tools


  2. run mraa-gpio list



    debian@beaglebone:~$ mraa-gpio list

  3. i connected the sensor to P9 GPIO_60


  4. generate the py file



    import mraa

    import time



    x = mraa.Gpio(58)

    x.dir(mraa.DIR_IN)



    while True:

    print x.read()

    time.sleep(1)


  5. run the py file, here is the output.





    debian@beaglebone:~$ python mraa_pur.py
