+Kernel driver HS3001
+===================
+
+Supported chips:
+
+  * Renesas HS3001, HS3002, HS3003, HS3004
+
+    Prefix: 'hs3001'
+
+    Addresses scanned: -
+
+    Datasheet: https://www.renesas.com/us/en/document/dst/hs300x-datasheet?r=417401
+
+Author:

+  - Andre Werner <andre.werner@systec-electronic.com>
+
+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.
+
