代码

重要：在创建 I2cDevice 之前，请确保正确设置了 I2C 引脚，特别是 ESP32，请确保安装了 nanoFramework.Hardware.ESP32 nuget。

//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the I2C GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);

对于 STM32 等其他设备，请确保您正在使用预设的 I2C 总线引脚。

I2cConnectionSettings settings = new I2cConnectionSettings(1, Shtc3.DefaultI2cAddress);
I2cDevice device = I2cDevice.Create(settings);

using (Shtc3 sensor = new Shtc3(device))
{
    Debug.WriteLine($"Sensor Id: {sensor.Id}");

    while (true)
    {
            if (sensor.TryGetTemperatureAndHumidity(out var temperature, out var relativeHumidity))
            {
                Debug.WriteLine($"Temperature: {temperature.DegreesCelsius:0.#}\u00B0C");
                Debug.WriteLine($"Relative humidity: {relativeHumidity.Percent:0.#}%");
                // WeatherHelper supports more calculations, such as saturated vapor pressure, actual vapor pressure and absolute humidity.
                Debug.WriteLine($"Heat index: {WeatherHelper.CalculateHeatIndex(temperature, relativeHumidity).DegreesCelsius:0.#}\u00B0C");
                Debug.WriteLine($"Dew point: {WeatherHelper.CalculateDewPoint(temperature, relativeHumidity).DegreesCelsius:0.#}\u00B0C");
                Debug.WriteLine();
            }

        sensor.Sleep();

        Thread.Sleep(1000);
    }

}
