SHT4x - Temperature & Humidity Sensor

SHT4x is a temperature and humidity sensor from Sensirion. This project supports the SHT40, SHT41, and SHT45 sensors.

Documentation

• SHT40 datasheet

Usage

Hardware Required

• SHT40.

Code (synchronous)

I2cConnectionSettings settings =
    new I2cConnectionSettings(1, Sht4x.DefaultI2cAddress);

using I2cDevice device = I2cDevice.Create(settings);
using Sht4x sensor = new Sht4x(device);

// read humidity (%)
double humidity = sensor.RelativeHumidity.Percent;
// read temperature (℃)
double temperature = sensor.Temperature.Celsius;

Code (asynchronous)

I2cConnectionSettings settings =
    new I2cConnectionSettings(1, Sht4x.DefaultI2cAddress);

using I2cDevice device = I2cDevice.Create(settings);
using Sht4x sensor = new Sht4x(device);

// Read both humidity and temperature.
(RelativeHumidity? rh, Temperature? t) =
    await sensor.ReadHumidityAndTemperatureAsync();

if(rh is null || t is null)
{
    throw new Exception("CRC failure");
}

// read humidity (%)
double humidity = rh.Value.Percent;
// read temperature (℃)
double temperature = t.Value.Celsius;
