| 19 | Description | |
| 20 | ----------- | |
| 21 | ||
| 22 | The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package. | |
| 23 | The difference between the two devices is that the HIH-6131 has a condensation | |
| 24 | filter. | |
| 25 | ||
| 26 | The devices communicate with the I2C protocol. All sensors are set to the same | |
| 27 | I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27) | |
| 28 | can be used in the board setup code. | |

31 | instantiate I2C devices. |
