A room air conditioning system has three inputs. There is $1$ PIR sensor$,1$ Button and $IR$ receiver installed in the room.

Requirement:

If the PIR sensor detects movement while the window is closed, the system should begin to operate. If the PIR sensor detects movement while the window is open it will be checked to see if the correct code $(77)$ has been received by the IR receiver and if the signal is not received, the syitem will not operate, if the correct code $($TT$)$ is received then it will begin to operate. Once it begins to operate it should run $20$ minutes, after $20$ minutes it should check the inputs to decide to operate or not $($Air conditioning aystem should be presented as an output, simply, $0-$system stops $1-$system operates$).$

i$)$ Draw the circuit and connections you planned $($lust like drawing on TinkerCad$)(10$pointi$)$

Witho the necessary code for the correct operation of the system $($AOpointa$)$
