Need help with Arduino code for digital AC config
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.)
