connecting Grove sensors to Respeaker 4-mic array

Products & Technology ReSpeaker
#1

Hello world,



I have a circular 4-mic respeaker array on which there are two Grove ports available.



I also have two Grove sensors

  1. an ultrasonic ranger
  2. sound detection



    I was hoping to be able to plug at least one of them into one of Respeaker Grove sockets and make them operational, however, without success.



    What library should I use ?



    Any piece of information would be helpful.

Hi,



For grove-ultrasonic sensor, please plug into gpio12, NOT I2C. then follow below instructions.



pi@raspberrypi:~ $ git clone https://github.com/Seeed-Studio/grove.py.git

pi@raspberrypi:~ $ cd grove.py/

pi@raspberrypi:~/grove.py $ sudo python setup.py install

pi@raspberrypi:~/grove.py $ cd grove

pi@raspberrypi:~/grove.py/grove $ python grove_ultrasonic_ranger.py 12

Hi!



I have similar problem but with Grove - PIR Motion Sensor. I’ve followed the instructions above, but instead of the last tep, I did:

python grove_mini_pir_motion_sensor.py 12



the result is nothing - no error, no return of any values. I’m also not sure that mini pir is correct choice since i have a regular pir motion sensor.



UPDATE: when I run ultrasonic ranger - I start to receive some output, with worning that it is incorrect. (Obviously, since I plugged motion sensor).





Best regards,

Andrei

Hi there,



I tested the min pir and pir with connection to GPIO 12. both of them work. For more info, please refer to instruction from <LINK_TEXT text=“https://github.com/Seeed-Studio/grove.p … /README.md”>https://github.com/Seeed-Studio/grove.py/blob/master/README.md</LINK_TEXT>



pi@raspberrypi:~ $ grove_mini_pir_motion_sensor 12
