Description |
|
----------- |
|
|
|
This driver implements support for the Sensirion SHTC1, SHTW1, and SHTC3 |
|
chips, a humidity and temperature sensor. Temperature is measured in degrees |
|
celsius, relative humidity is expressed as a percentage. |
|
|
|
The device communicates with the I2C protocol. All sensors are set to I2C |
|
address 0x70. See Documentation/i2c/instantiating-devices.rst for methods to |
|
instantiate the device. |
|
|
|
There are two options configurable by means of shtc1_platform_data: |
|
|
|
1. blocking (pull the I2C clock line down while performing the measurement) or |
|
non-blocking mode. Blocking mode will guarantee the fastest result but |
|
the I2C bus will be busy during that time. By default, non-blocking mode |
|
is used. Make sure clock-stretching works properly on your device if you |
|
want to use blocking mode. |
|
2. high or low accuracy. High accuracy is used by default and using it is |
|
strongly recommended. |
