Need help with Arduino code for digital AC config

[Discseven]

EDIT: Collaboration established.



Am putting together Arduino components to sense temp & humidity and to serve as a thermostatic controller for 911 AC system.* Collected data will be fed to a 4x20 LCD. "Set Temp" will be controlled by a potentiometer with temp target displayed on LCD.

Hardware for this I can handle. Am looking for an Arduino sketch expert to help with the code.

* System: 2 temp & humidity sensors, 2 temp sensors, 1 Arduino Uno, 1 4x20 LCD, resistors and potentiometers as required.

Collected sensor data:

Cabin temp
Cabin humidity
Evaporator core temp
Duct temp
Exterior ambient
Exterior humidity

Set:

Target temp (with some hysteresis)

7 data points will be displayed: 2 items per line on 4x20 LCD. "Set Temp" on top line by itself.
If/Then = IF "Cabin temp" is =>2 degrees F compared to "Set Temp", THEN compressor & fan circuit is closed (AC is ON.) If "Cabin temp" =< "Set Temp"< THEN compressor & fan circuit is open (AC is OFF.)

I have not idea, but a suggestion. If you do not get a reply here, you could try posting in the "off topic forum", there seems to be quite a few techies there.

^^^ Good idea.

I could do it and am local to you. Send me an email or PM. I have arduino and breadboard but would need the specific sensors you are using or we can even discuss which to get.

Check out my sig

I would suggest you ask on an electronics hobbyist forum, like www.hackaday.io. More people there will have Arduino experience.

PM'd you Dr J. If I interpret correctly... your WUR is Arduino-driven. Damm technofine!
