| 14 | Description | |
| 15 | ----------- | |
| 16 | ||
| 17 | The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package. | |
| 18 | The difference between the two devices is that the HIH-6131 has a condensation | |
| 19 | filter. | |
| 20 | ||
| 21 | The devices communicate with the I2C protocol. All sensors are set to the same | |
| 22 | I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27) | |
| 23 | can be used in the board setup code. | |
| 24 | ||
| 25 | Please see Documentation/i2c/instantiating-devices for details on how to | |
| 26 | instantiate I2C devices. | |
