10. Fig. BS is logic circuit for a warning system for a greenhouse. Once the gardener or caretaker has switched the system on, he wants to be warned by the following conditions: 1. if the greenhouse gets too cold or [6marks) II. if someone has opened the door. [6marks] A Closed = 1 NOT gate gives output of 1 if door open Magnetic switch on door OR gate gives output of 1 if door open or greenhouse cold Open - NOT D B Hot-1 OR E Temperature sensor Cold 0 AND gate gives output of 18 system is switched on and output of OR gate is 1 G Warning light NOT gate gives output of 1 F on-1 C if greenhouse cold Main system switch Off-0 ANO AND Fig B5 Use the figure to answer the flowing questions: i. Verify using truth table the conditions that may trigger a warning light. ii. Develop a Boolean expression for the system in fig B5 [6marks) [6marks]
