# HTS221

Arduino library to support the HTS221 capacitive digital sensor for relative humidity and temperature

## API

This sensor uses I2C to communicate. It is then required to create a TwoWire interface before accessing to the sensors:  

    TwoWire dev_i2c(I2C_SDA, I2C_SCL);  

    dev_i2c.begin();

An instance can be created and enabled following the procedure below:  

  For the humidity sensor:  

    HTS221Sensor HumTemp(&dev_i2c);

    HumTemp.begin();

    HumTemp.Enable();  

The access to the sensor values is done as explained below:  

  Read humidity and temperature.  

    float humidity;

    float temperature;

    HumTemp.GetHumidity(&humidity);  

    HumTemp.GetTemperature(&temperature);
