The HY-SRF05 ultrasonic sensor uses sonar to determine distance to an object (like bats). It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package.

Code Example​

Hysrf05 hYSRF05;

public override Task Initialize()
{
    hYSRF05 = new Hysrf05(
        device: Device, 
        triggerPin: Device.Pins.D05, 
        echoPin: Device.Pins.D06);
    hYSRF05.DistanceUpdated += HYSRF05_DistanceUpdated;

    return Task.CompletedTask;
}

public override Task Run()
{
    while (true)
    {
        // Sends a trigger signal
        hYSRF05.MeasureDistance();
        Thread.Sleep(500);
    }

    return Task.CompletedTask;
}

private void HYSRF05_DistanceUpdated(object sender, IChangeResult<Meadow.Units.Length> e)
{
    Console.WriteLine($"Distance is {e.New.Centimeters}cm");
}

Wiring Example​

The HY-SRF05 sensor has 5 pins, but you’ll only connect 4: power, ground, echo and trigger (out isn’t used).
