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