The Veris TEX00 temperature sensor family is made up of a series of
RTD thermistors in wall mount packaging.
This driver was developed using the TED00, which utilizes a 10K Ohm
Type 2 thermistor. However, this driver can support the other 12
variants of the TE series as well by providing the correct sensor type
to the class constructor. These other sensor types have not been
tested. Only the TED00 hardware was tested with this driver.
This sensor must be connected as part of a voltage divider, with the
balancing resistor ideally matched to the sensor's 25C detection
range. For the TED00 (10kt2), a 10K Ohm (1% tolerance) resistor was
used in a circuit like the following:
GND o----|TED00(10k2)|----o----|balanceResistor(10K)|----o VCC (+5vdc)
|
|
|----o A0 (analog input to MCU)
A 3.3vdc voltage can be used as well if desired.

The driver adds support for the Veris TEAMS Temperature Transmitter.
It provides it's output via a 4-20ma current loop. The supported
temperature range is 10C to 35C.
This sensor was developed with a Cooking Hacks (Libelium)
4-channel 4-20ma Arduino interface shield. For this interface,
the receiver resistance (rResistor) was specified as 165.0
ohms.

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.
