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 Documentation/i2c/instantiating-devices.rst for methods |
|
to instantiate the device. |
