    Code

    Important: make sure you properly setup the I2C pins especially for ESP32 before creating the I2cDevice, make sure you install the 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);
    

    For other devices like STM32, please make sure you're using the preset pins for the I2C bus you want to use.

    I2cConnectionSettings settings = new I2cConnectionSettings(1, (byte)I2cAddress.AddrLow);
    I2cDevice device = I2cDevice.Create(settings);
    
    using (Sht3x sensor = new Sht3x(device))
    {
        // read temperature (℃)
        double temperature = sensor.Temperature.Celsius;
        // read humidity (%)
        double humidity = sensor.Humidity;
        // open heater
        sensor.Heater = true;
    }
