| 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. | |
