AC controller(Raspberry pi/ Arduino/ Micro Controller based) working on temperature setting.

Air Conditioner controller(Raspberry Pi/ Arduino/ Micro Controller based) working on the temperature setting to operate two ACs in sequencing(AC1 and AC2).


1. Ambient temperature will be calculated by temperature sensors. (T1, T2, T3)

Average of 3 temperatures will be TAVG= (T1+T2+T3)/3

2. Tavg will be used as a reference temperature. (RT=Tavg)

3. Input will be the desired temperature set by the user. (ST)

4. Let ACT1 and ACT2 will be set temperatures of AC1 and AC2 respectively.


When RT>ST,

at RT=ST+2;

AC1 will be turned ON at ACT1=ST-2;

After 5 minutes, Check for RT=ST;

again if RT>ST;

Decrease AC1 temp by 2 degree


Again After 5 minutes, Check for RT=ST;

again if RT>ST;

Turn on AC2 also at ACT2=ST-4;

Run Both AC till RT=ST;

When RT =ST, Power off AC1;

Run AC2 till RT=ST-4.

At RT=ST-4 turn off AC2;




RT>ST; hence AC1 will turn on at ST-2 i.e. ACT1=20;

After 5 minutes, Check for RT=ST;

again if RT>ST;

Decrease AC1 temp by 2 degree


Again After 5 minutes, Check for RT=ST;

again if RT>ST;

Turn on AC2 also at ACT2=ST-18;

Run Both AC till RT=ST=22;

When RT =ST,=22 Power off AC1;

Run AC2 till RT=ST-4=18.

At RT=ST-4=18 turn off AC2;

Also, the need for UI for mobile. The data logging function also.
