Smart Garage Utilizing Internet of Things (IoT)

Algorithm 1

Entrance algorithm.

1. do

2. Check the garage until there is an empty location.

3. While (number of parking slot =0) ;the garage is full

4. While (entrance RFID=value)

5. scanning the RFID UID.

6. Check and match presence of UID in the database.

7.  If (UID invalid)

8.   Print invalid UID

9.  else

10.   Open the entrance gate and turn RGB led to green.

11.    If (entrance gate sensor D>threshold 4cm)

12.     Close the gate and turn RGB led to red

13.     Start scanning the slots

14.      If (empty slot number ≠0)

15.       Decrement number of empty slots at Lcd

16.       send the empty slot locations to

17.       application via Node MCU

18.      Else

19.       Print Garage is full at LCD

20.       send the Garage is full in application

21.      End if

22.    End if

23.  End if

24. End while
