Quote: "If you're planning to have the sensor in a bright area and use a 10KΩ pulldown, it will quickly saturate. That means that it will hit the 'ceiling' of 5V and not be able to differentiate between kinda bright and really bright. In that case, you should replace the 10KΩ pulldown with a 1KΩ pulldown. In that case, it will not be able to detect dark level differences as well but it will be able to detect bright light differences better. This is a tradeoff that you will have to decide upon!"

Galvanic separation should be considered as a design philosophy, so serial coupling (and 5V transport) of outlet units can be made possible

Configuration in init.d

Make sure to check the wiki page

Describe which parts of the GUI that needs to be developed.
Prioritize those

5V PSU design should be revisited, so enough power can be supplied to MOU and n number of Outlets (see also galvanic separation issue)

Set temperature on pH sensor before read. C code

From http://atlas-scientific.com/_files/pH_Circuit_4.0.pdf:

I Instructs the pH Circuit to transmit it version number.
A comma separated string will be transmitted that will contain 3 values.

1. The type of device:
2. The firmware version number:
3. The firmware version date:
   Full proper syntax: i or I
   The pH Circuit will respond: P,V4.0,8/12
