From 27f8b1355504744e7cfbb5756f120734d58644a8 Mon Sep 17 00:00:00 2001 From: Iain Paton Date: Wed, 27 Jun 2012 08:55:11 +0000 Subject: hwmon: Honeywell Humidicon HIH-6130/HIH-6131 humidity and temperature sensor driver This is a new driver for the Honeywell Humidicon HIH-6130/HIH-6131 humidity sensor. The driver is based on the existing Sensiron sht21 driver with the necessary changes to the probe, update_measurements and conversion functions necessary to use the Honeywell sensors. There's no difference between the 6130 & 6131 other than the 6131 having an external condensation filter attached.
