A smart greenhouse system uses three inputs to control a water pump.

The water pump (P) switches on (output is 1) if all of the following conditions are met:

  • the moisture sensor (M) is off (0)
  • the temperature sensor (T) is on (1)
  • the manual override switch (S) is on (1)

Complete the logic circuit to represent this system.

A logic circuit template with three input terminals on the left labeled M, T, and S, and a single output terminal on the right labeled P.

Your circuit must use only standard 2-input AND gates and 1-input NOT gates.
