Usage

I2cConnectionSettings settings = new I2cConnectionSettings(1, Ags01db.DefaultI2cAddress);
I2cDevice device = I2cDevice.Create(settings);

using (Ags01db sensor = new Ags01db(device))
{
    // read AGS01DB version
    byte version = sensor.Version;

    // read VOC concentration
    double concentration = sensor.Concentration;
}

Example

Hardware Required

• AGS01DB
• 4.7kΩ resistance × 2
• Male/Female Jumper Wires

Circuit

• SCL - SCL
• SDA - SDA
• VCC - 5V
• GND - GND

SDA, SCL need pull-up resistance.

Code

I2cConnectionSettings settings = new I2cConnectionSettings(1, Ags01db.DefaultI2cAddress);
I2cDevice device = I2cDevice.Create(settings);

using (Ags01db sensor = new Ags01db(device))
{
    // read AGS01DB version
    Console.WriteLine($"Version: {sensor.Version}");
    Console.WriteLine();

    while (true)
    {
        // read concentration
        Console.WriteLine($"VOC Gas Concentration: {sensor.Concentration}ppm");
        Console.WriteLine();

        Thread.Sleep(3000);
    }
}
