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;
}
