This driver implements support for the Sensirion SHTC1, SHTW1, and SHTC3
chips, a humidity and temperature sensor. Temperature is measured in degrees
celsius, relative humidity is expressed as a percentage.

1. blocking (pull the I2C clock line down while performing the measurement) or
non-blocking mode. Blocking mode will guarantee the fastest result but
the I2C bus will be busy during that time. By default, non-blocking mode
is used. Make sure clock-stretching works properly on your device if you
want to use blocking mode.
2. high or low accuracy. High accuracy is used by default and using it is
strongly recommended.
