Kernel driver sht4x
Supported Chips:
* Sensirion SHT4X
Prefix: 'sht4x'
Addresses scanned: None
Author: Navin Sankar Velliangiri <>
This driver implements support for the Sensirion SHT4x chip, a humidity
and temperature sensor. Temperature is measured in degree celsius, relative
humidity is expressed as a percentage. In sysfs interface, all values are
scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
Usage Notes
The device communicates with the I2C protocol. Sensors can have the I2C
address 0x44. See Documentation/i2c/instantiating-devices.rst for methods
to instantiate the device.
