The HCSENS0040 is a microwave motion detector commonly found on the RCWL-0516 board. It detects relative motion using the doppler effect. It uses a single GPIO pin to notify Meadow when motion is detected.

Code Example​

private Hcsens0040 sensor;

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

    sensor = new Hcsens0040(Device.CreateDigitalInterruptPort(Device.Pins.D05, Meadow.Hardware.InterruptMode.EdgeBoth));
    sensor.OnMotionDetected += Sensor_OnMotionDetected;

    return Task.CompletedTask;
}

private void Sensor_OnMotionDetected(object sender)
{
    Resolver.Log.Info($"Motion detected {DateTime.Now}");
}
