Describe the typical location of an entry level integrated computer, also called an integrated controller, and what it controls
What will be an ideal response?
It is typically located in the greenhouse. It has a limited number of inputs
from sensors and outputs to equipment it controls. It may receive signals from all
sensors in a greenhouse section and control all of the equipment in that section.
Alternatively, it might receive signals and control equipment in a few greenhouse
sections, but the amount of equipment would have to be limited to the small
capacity of the controller.
