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);
