Trying to control a Brightsign AU335 over GPIO using a motion sensor

Hello,

I am very new to Brightsign and my wiring knowledge is bad. I am trying to trigger my Brightsign AU335 to play an audio file whenever my connected motion sensor detects movement. However I am unfamiliar with GPIO wiring. Which are the correct GPIO ports to use, to wire my motion sensor to my AU335?

    You could wire your sensor as follows:

    - Ground to pin 1

    - VCC to pin 2

    - Trigger to pin 3

    Bear in mind, brightsigns can supply up to 3.3v. If your sensor requires more power you will need an external power supply.

    When it comes to the sensor voltage on the input pin, anything below 0.8V with be considered "low", anything above 2v will be considered "high".

    So in your project, use the GPIO number corresponding to the button number in the pinout above (Eg: Button 0 on pin 3 is GPIO 0). Use this trigger state to swap on either a "down" or "Up" event (depending on your sensor voltage change)

    Hello,

    Wiring a motion sensor to your BrightSign AU335 for audio playback is straightforward. The AU335 has a 12-pin Phoenix GPIO port with 8 bi-directional GPIOs. You'll use one of these GPIO pins as an input and connect it to a Ground (GND) pin on the same port. Your motion sensor should ideally provide a contact closure or pull its signal to ground upon detection. Connect one signal wire from the motion sensor to your chosen GPIO input (e.g., GPIO 0) and the other signal wire (its common or ground) to a BrightSign GND pin. Remember to power your motion sensor separately if needed. Finally, in BrightAuthor:connected software, configure the selected GPIO pin as an input and set up an event to trigger your audio file when the sensor detects movement.

     

    Best regards,
