The project conditions are:The project functionality will be provided as per the project description suppliedbelow.You must present/demonstrate the project as a group, at the given time,andwithin a given time limit ( 20 mins ).A soft copy of all project documents is required before you The program functionality should be as follows:• Upon entering the “run” mode all counters/timers must be reset (use the first scan bit).• When students scan RFID cards, the opening motor automatically opens the door and closing motor closes it after a 5 second wait.• The current number of students should be counted by incrementing/decrementing as students enter or leave the classroom. • The number of students entering the classroom is counted using a reflective sensor, while the number leaving is counted using a fiber optic sensor. The count should be displayed in the decimal tag "Total no of students”.• The maximum number of students in the classroom is 20, and when the classroom is occupied by the students performs the following tasks. Task-1:The lighting system must be activated as follows:• Lighting row 1 turns on when the number of students is less than 10.• Lighting rows 1 and 2 turn on when the number of students is greater than 10 and less than 15.• Lighting rows 1, 2, and 3 turn on when the number of students exceeds 18. Task-2:The Air conditioner shall be activated as below:• The air conditioner turns ON and operates at 40% speed when the number of students in the class is less than or equal to 8.• The air conditioner turns ON operates at 60% speed when the number of students in the class is between 9 and 16, and the thermostat is ON.• The air conditioner turns ON operates at 100% speed when the number of students in the classroom exceeds 16, and the thermostat is ON.(the percentage of Air conditioner speeds must be displayed on the 4 to 20 ma level display box)Page 7 of 9Task-3: When smoke is detected inside the classroom at any time the following actions must be taken:• The external fire alarm should immediately activate (with a 60% duty cycle and a period of 5 seconds), latching in the ON state.• All the appliances are turned OFF.• The door automatically opens with the help of the door opening motor.• The emergency light turns ON (with a 75% duty cycle and a period of 6 seconds).• The fire extinguisher turns ON (with a 50% duty cycle with a period of 8 seconds).• Once the smoke detection sensor is deactivated, the alarm is reset, and all appliances are turned ON based on the conditions. The door should be closed, the emergency light must be turned OFF, and the fire extinguisher must remain OFF.
