Si7021 - Temperature & Humidity Sensor

The Si7021 device provides temperature and humidity sensor readings with an I2C interface.

Documentation

Board

Sensor image Si7021 sensor

Usage

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.

Hardware Required

  • Si7021
  • Male/Female Jumper Wires

Circuit

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

Code

I2cConnectionSettings settings = new I2cConnectionSettings(1, Si7021.DefaultI2cAddress);
I2cDevice device = I2cDevice.Create(settings);

using (Si7021 sensor = new Si7021(device, Resolution.Resolution1))
{
    while (true)
    {
        var tempValue = sensor.Temperature;
        var humValue = sensor.Humidity;

        Debug.WriteLine($"Temperature: {tempValue.Celsius:N2}\u00B0C");
        Debug.WriteLine($"Relative humidity: {humValue:N2}%");

        // WeatherHelper supports more calculations, such as saturated vapor pressure, actual vapor pressure and absolute humidity.
        Debug.WriteLine($"Heat index: {WeatherHelper.CalculateHeatIndex(tempValue, humValue).Celsius:N2}\u00B0C");
        Debug.WriteLine($"Dew point: {WeatherHelper.CalculateDewPoint(tempValue, humValue).Celsius:N2}\u00B0C");
        Debug.WriteLine();

        Thread.Sleep(1000);
    }
}
