The driver was developed using the Veris CWLSHTA CO2 Gas sensor. The
'T' variant supports a temperature sensor, and the 'H' variant
supports a humidity sensor.
All 3 signals are provided by the device as analog 0-5Vdc, 0-10Vdc, or
4-20ma loop current outputs. For devices supporting temperature, the
valid temperature range is 10C to 50C. The humidity ranges from 0% to
100% (non-condensing). The CO2 sensor ranges from 0 to 2000 ppm.
This driver was developed using the 5Vdc outputs and the 4-20ma
outputs. For voltage outputs, your MCU must be configured for 5V
operation. In addition, you must configure the sensor (via it's
configuration switches) to output 0-5VDC only. Using any other analog
reference voltage will require the appropriate external circuitry
(such as a voltage divider) in order to interface safely with your
MCU.
In addition, the sensor can be configured for 4-20ma usage, by
specifying the correct receiver resistance (in ohms) in the
constructor. This sensor was tested with a Cooking Hacks (Libelium)
4-channel 4-20ma Arduino interface shield. For this interface, the
receiver resistance was specified as 165.0 ohms.

An ADS1015 implementation existed in the inferface fork before the ADS1x15
moulde was added to upstream repo. This retrofits the IADC interface onto
an implementation derived from ads1x15

This is required so that interface include files are taken from
local src folder before looking in /usr/include/upm where an older version
may exist.

DS1808 is a general purpose potentiometer but this implementation
is limited to controlling brightness of custom LED lighting hardware.
Ideally there should be a DS1808 module used by a seperate
lighting module.

This driver has been rewritten to support some new functionality, be
more generic and fix up some old bugs. Multiple MY9221's can now be
chained together and are supported by the MY9221 base class.
In addition, the Grove LED Bar and Grove Circular LED drivers have
been incoporated into the my9221 library, using the new MY9221 class
as their base class. Examples have been fixed to work with the new
library, and renamed where needed.
The current grovecircularled driver has been removed as it is now a
part of the my9221 library.
