A driver for the HTU21D-F temperature and humidity sensor. :param i2c_bus: The
busio.I2Cobject to use. This is the only required parameter. :param int address: (optional) The I2C address of the device.
Starts a measurement. Starts a measurement of either
TEMPERATUREdepending on the
whatargument. Returns immediately, and the result of the measurement can be retrieved with the
relative_humidityproperties. This way it will take much less time. This can be useful if you want to start the measurement, but don’t want the call to block until the measurement is ready – for instance, when you are doing other things at the same time.
The measured relative humidity in percent.
The measured temperature in degrees Celcius.
