Remarks

Dht10
Status
Source code GitHub
NuGet package

The DHT10 is a low-cost humidity and temperature sensor that communicates over the I2C bus.

-40 to 80 celius +/- 0.5 degrees 0 to 99.9% humidity +/- 3% relative humidity

Code Example

public class MeadowApp : App<F7Micro, MeadowApp>
{
    Dht12 sensor;

    public MeadowApp()
    {
        sensor = new Dht12(Device.CreateI2cBus());

        sensor.StartUpdating();

        sensor.Updated += SensorUpdated;
    }

    void SensorUpdated(object sender, Meadow.Peripherals.Sensors.Atmospheric.AtmosphericConditionChangeResult e)
    {
        Console.WriteLine($"Humidity: {e.New.Humidity}%, Temperature: {e.New.Temperature}°C");
    }
}
