The Parallax PIR detects motion via infrared. It emits a high signal over the data pin when motion is detected. The pin returns to a low state when motion stops.

Code Example

private ParallaxPir parallaxPir;

public override Task Initialize()
{
    Resolver.Log.Info("Initialize...");

    parallaxPir = new ParallaxPir(Device.CreateDigitalInterruptPort(Device.Pins.D05, InterruptMode.EdgeBoth, ResistorMode.Disabled));

    parallaxPir.OnMotionStart += (sender) => Resolver.Log.Info($"Motion start  {DateTime.Now}");
    parallaxPir.OnMotionEnd += (sender) => Resolver.Log.Info($"Motion end  {DateTime.Now}");

    return Task.CompletedTask;
}
