Question 2

An automated greenhouse ventilation system controls a fan ( $F$ ).

The fan will turn on if:

the humidity sensor ( $H$ ) detects high humidity
or the temperature sensor ( $T$ ) detects high temperature
and the manual shutdown switch ( $S$ ) is not activated.

Construct a logic statement, using the operators AND, OR, and NOT with the letters $H$ , $T$ , and $S$ , to show the conditions under which the fan will turn on.
