Sous vide (in progress)

Remark: Logic for a sous vide system

Set lo
w_temperature
Set high_temperature
Set start_time
Set end_time
Turn on heat
Turn on led
if end_time < start_time then stop.

loop until time > end_time.
    Get temperature
    if temperature > high_temperature then turn off heat and turn off led
    if temperature < low_temperature then turn on heat and turn on led
    get time

loop
turn led off
end

The more I thought about this , it came to me you could use the same idea for an air conditioning system controller. of course the logic would have to be a bit different.

Set lo
w_temperature
Set high_temperature
Set mid temp range
Set low temperature
Set start_time
Set end_time
Turn off Heater and AC
Turn on led
if end_time < start_time then stop.

loop until time > end_time.
    Get temperature
    if temperature > high_temperature then turn on the AC and turn off the heat   
     if temperature = mid_temperature then turn off both the AC and the Heater
     if temperature < low_temperature then turn on heat and turn off the AC
    get time

loop
turn led off
end
