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:
dev_i2c = new TwoWire(I2C2_SDA, I2C2_SCL);
dev_i2c->begin();
An instance can be created and enbaled following the procedure below:
For the humidity sensor:
HumTemp = new HTS221Sensor (dev_i2c);
HumTemp->Enable();
The access to the sensor values is done as explained below:
Read humidity and temperature.
HumTemp->GetHumidity(&humidity);
HumTemp->GetTemperature(&temperature);
