1.1 GREENHOUSE AUTOMATIC VENTILATION PANE CONTROL
The owner of a greenhouse would like to acquire an installation to manage the opening
and closing of the ventilation window panes located on the greenhouse roof.
The greenhouse has two window panes to provide ventilation. The opening of these
window panes is controlled by a motor and 2 sensors that indicate whether the window
panes are open or closed:
During the day, the window panes open to ventilate the structure from 12:00 to 15:00, at
the time of day when, in principle, the temperature is the highest. However, if the
temperature is less than 10Â°C, the window panes do not open, or when they are already
open, they close.
In addition, the window panes open during the day when the temperature reaches 25Â°C. If
the temperature falls below 25 Â°C, the window panes must close again.
Finally, at night, the window panes remain closed regardless of the temperature.
