22 This driver implements support for the Sensirion SHT3x-DIS chip, a humidity
23 and temperature sensor. Temperature is measured in degrees celsius, relative
24 humidity is expressed as a percentage. In the sysfs interface, all values are
29 Documentation/i2c/instantiating-devices.rst for methods to instantiate the device.
31 Even if sht3x sensor supports clock-strech(blocking mode) and non-strench
32 (non-blocking mode) in single-shot mode, this driver only supports the latter.
