Question 5

An automated warehouse cooling system turns on a ventilation fan. The fan must only be triggered if:

  • the main power (P) is switched on
  • the automated mode (A) is enabled
  • the heat sensor (H) or the humidity sensor (M) has triggered a high reading.

Construct a Boolean expression, using AND, OR and NOT with the letters P, A, H, and M to show the conditions that will trigger the ventilation fan.
