/* $NetBSD: sht4xreg.h,v 1.2 2022/05/24 06:28:01 andvar Exp $ */
A driver for the Sensirion SHT40/SHT41/SHT45 temperature and humidity sensor. An example of this chip is: https://www.adafruit.com/product/4885 This is a lower cost chip that provides higher then usual precision according to the data sheet. This driver supports all of the published functions that the chip has.
