Atlas Scientific analog gravity dissolved oxygen sensor

The AtlasScientificGravityDOMeter library is included in the Meadow.Foundation.Sensors.Environmental.AtlasScientificGravityDOMeter 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.Environmental.AtlasScientificGravityDOMeter


AtlasScientificGravityDOMeter sensor;

public override Task Initialize()

    sensor = new AtlasScientificGravityDOMeter(Device.Pins.A01);
    sensor.CalibrationInAir = new Voltage(0.04, Voltage.UnitType.Volts);

    // Example that uses an IObservable subscription to only be notified when the saturation changes
    var consumer = AtlasScientificGravityDOMeter.CreateObserver(
        handler: result =>
            string oldValue = (result.Old is { } old) ? $"{old * 100:n1}" : "n/a";
            string newValue = $"{result.New * 100:n1}";
            Resolver.Log.Info($"New: {newValue}%, Old: {oldValue}%");
        filter: null

    // optional classical .NET events can also be used:
    sensor.Updated += (sender, result) =>
        string oldValue = (result.Old is { } old) ? $"{old * 100:n0}%" : "n/a";
        Resolver.Log.Info($"Updated - New: {result.New * 100:n0}%, Old: {oldValue}");

    return Task.CompletedTask;

public override async Task Run()

    await ReadSensor();

    //example calibration setting, ensure the sensor is set up for calibration 
    var calibrationVoltage = await sensor.GetCurrentVoltage();
    sensor.CalibrationInAir = calibrationVoltage;

    Resolver.Log.Info($"Calibration voltage: {calibrationVoltage.Volts}V");


protected async Task ReadSensor()
    var saturation = await sensor.Read();
    Resolver.Log.Info($"Initial saturation: {saturation * 100:N1}%");
