Meadow.Foundation.Sensors.Environmental.Pmsa003i 1.12.2.5-beta

Meadow.Foundation.Sensors.Environmental.Pmsa003i

PMSA003I I2C particulate matter AQI sensor

The Pmsa003i library is included in the Meadow.Foundation.Sensors.Environmental.Pmsa003i 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.

Installation

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.Pmsa003i

Usage

Pmsa003i pmsa003i;

public override Task Initialize()
{
    var bus = Device.CreateI2cBus(I2cBusSpeed.Standard);
    pmsa003i = new Pmsa003i(bus);

    pmsa003i.Updated += Pmsa003i_Updated;

    return base.Initialize();
}

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

    pmsa003i.StartUpdating(TimeSpan.FromSeconds(2));

    return base.Run();
}
