Description

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 How to instantiate I2C devices for methods to instantiate the device.

Sysfs entries

temp1_input	Measured temperature in millidegrees Celsius
humidity1_input	Measured humidity in %H
update_interval	The minimum interval for polling the sensor, in milliseconds. Writable. Must be at least 2000.
