| Description |
| ----------- |
| |
| This driver implements support for the Renesas HS3001 chips, a humidity |
| and temperature family. Temperature is measured in degrees celsius, relative |
| humidity is expressed as a percentage. In the sysfs interface, all values are |
| scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500. |
| |
| The device communicates with the I2C protocol. Sensors have the I2C |
| address 0x44 by default. |
