-There are two options configurable by means of sht3x_data:

+   high or low accuracy. High accuracy is used by default and using it is
    strongly recommended.
 
+Even if sht3x sensor supports clock-strech(blocking mode) and non-strench
+(non-blocking mode) in single-shot mode, this driver only supports the latter.

 The sht3x sensor supports a single shot mode as well as 5 periodic measure
 modes, which can be controlled with the update_interval sysfs interface.
 The allowed update_interval in milliseconds are as follows:
