Jon Trulson 239ab49d6b sht1x: Initial implementation
This driver was developed with a DFRobot SHT10 Temperature and Humidity
sensor.  This driver should work on all SHT1X devices.

It requires a 10K pull-up resistor connected to the data pin.
The sensor can be run at differing voltages from 2.5v to 5v.
