- Description
- -----------
- This driver implements support for the Sensirion SHTC1 chip, a humidity and
- temperature sensor. Temperature is measured in degrees celsius, relative
- humidity is expressed as a percentage. Driver can be used as well for SHTW1
- chip, which has the same electrical interface.
- The device communicates with the I2C protocol. All sensors are set to I2C
- address 0x70. See Documentation/i2c/instantiating-devices 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.
