| | 40 | Description |
| | 41 | ----------- |
| | 42 | |
| | 43 | This driver implements support for the Sensirion SHTC1, SHTW1, and SHTC3 |
| | 44 | chips, a humidity and temperature sensor. Temperature is measured in degrees |
| | 45 | celsius, relative humidity is expressed as a percentage. |
| | 46 | |
| | 47 | The device communicates with the I2C protocol. All sensors are set to I2C |
| | 48 | address 0x70. See Documentation/i2c/instantiating-devices.rst for methods to |
| | 49 | instantiate the device. |
| | 50 | |
| | 51 | There are two options configurable by means of shtc1_platform_data: |
| | 52 | |
| | 53 | 1. blocking (pull the I2C clock line down while performing the measurement) or |
| | 54 | non-blocking mode. Blocking mode will guarantee the fastest result but |
| | 55 | the I2C bus will be busy during that time. By default, non-blocking mode |
| | 56 | is used. Make sure clock-stretching works properly on your device if you |
| | 57 | want to use blocking mode. |
| | 58 | 2. high or low accuracy. High accuracy is used by default and using it is |
| | 59 | strongly recommended. |
