Me007ys serial ultrasonic distance sensor

The Me007ys library is included in the Meadow.Foundation.Sensors.Distance.Me007ys nuget package and is designed for the Wilderness Labs Meadow .NET IoT platform.

This driver is part of the Meadow.Foundation peripherals library, an open-source repository of drivers and libraries that streamline and simplify adding hardware to your C# .NET Meadow IoT applications.

You can install the library from within Visual studio using the the NuGet Package Manager or from the command line using the .NET CLI:

dotnet add package Meadow.Foundation.Sensors.Distance.Me007ys


Me007ys me007ys;

public override Task Initialize()

    me007ys = new Me007ys(Device, Device.PlatformOS.GetSerialPortName("COM1"));

    var consumer = Me007ys.CreateObserver(
        handler: result =>
            Resolver.Log.Info($"Observer: Distance changed by threshold; new distance: {result.New.Centimeters:N1}cm, old: {result.Old?.Centimeters:N1}cm");
        filter: result =>
            if (result.Old is { } old)
                return Math.Abs((result.New - old).Centimeters) > 5.0;
            return false;

    me007ys.Updated += Me007y_DistanceUpdated;

    return Task.CompletedTask;

public override async Task Run()

    var distance = await me007ys.Read();
    Resolver.Log.Info($"Initial distance is: {distance.Centimeters:N1}cm / {distance.Inches:N1}in");


private void Me007y_DistanceUpdated(object sender, IChangeResult<Length> e)
    Resolver.Log.Info($"Distance: {e.New.Centimeters:N1}cm / {e.New.Inches:N1}in");
