AbstractEntering attendance is mandatory for every education system. Nowadays some universities are monitoring the attendance of students with aid of google forms. The consult faculties of the subject are asked to fill the google form after their respective class as per the scheduled timetable. This idea can be used to reduce the time consumption to fill the google form by the teachers. In this paper, also introduce the wiper board and automatic fan, and light control. Writing on a board is a very attractive way to teach students, but dusting the board may cause some allergic issues to lecturers while using the blackboard and it also consumes 5-10 min to rub the white or blackboard. If we use a wiper, or board it may reduce the board cleaning time so that it can be well utilized for the students. Electricity is very essential to humans so its humans responsibility to save electricity. This paper also concentrates on automatic light and fan on-off control to save electricity.

    All the institutions follow a formal way of taking attendance in class. This technology made it easy for the lectures just by entering a student count using the keypad. This data will be updated to the higher authority by using an IoT system. The most important whiteboard System in the field of educational is the basis of this paper, its aim is to reduce the work of lecturers to clean the board. The smart classroom system controls the automatic ON/OFF of the air conditioning system and lighting system based on the presence and absence of the person within the classroom. Smart classrooms using IOT is having various advantages in monitoring student performance and also gathering information about student and teacher academic records. The proposed system cleans the boards academic records. The proposed system cleans the board with the operated switch and controls the on and off of the light and fan based on the presence of the person in the classroom.


    [1] The automated systems however entail horizontal and vertical motion of the cleaning tool which spans across the board writing area. With the electronic boards which employs a unique writing mechanism, they incorporate a resistive layer extended over an inflexible substrate, an electronic module for defining instrument position i.e. pen and computer to process and store pen coordinates over the board

    [2] This paper presents the design and construction of a motorized sensing whiteboard that aims at making teaching efficient and reducing human efforts. The system consists of five basic units: – Flexible whiteboard surface material,

    microcontroller and sensor unit, dusters, plastic rollers, and motors.

    [3] The aim of the project is to create a control-based model that counts the number of people entering the room and illuminates the room based on the light of the room and turns on the fan automatically where the people are sitting inside the room. It is designed to prevent unwanted power in colleges, apartments, etc. The whole process is automated using its sensors

    [4] Michele Mango et al. proposed a low-cost, wireless, sensor-based based smart lighting system that makes use of PIR sensors and motion sensors. It helps to control light intensity and energy consumption.

    The microcontroller takes in output from the teacher by keypad for attendance of the students and which subject is taken, the data is uploaded to the web application adafruit io, and the access of the web application is given to HOD as shown in the figure 2. The data like the number of students present and respective teacher data will be given and monitored.

    The whiteboard cleaning mechanism is done by using a motor clockwise anti-clock mechanism to clean the whiteboard as shown in the figure 3. the switch is given to control the direction of the motor to clean. There are 2 switches used in this system, when switch 1 is on motor run clockwise so the duster moves forward and when switch 2 is pressed motor run anticlockwise so the duster moves backward.

    The person detection is done by the sensor to control the light and fan. If the person is detected in the classroom then the fan and light will be ON, if no motion or person is not found the fan and light will remain off as shown in figure 4.


    • In Schools and Colleges.

    • Fan and Light Control system-Some industries, homes, and other sectors.

    When the lecturer enters the password using a keypad LCD displays the respective name & subject after they enter the number the data will upload to the higher authority

    Dr. Santosh Herur, HOD, Department of ECE, JIT, Davanagere, for his support and encouragement in the completion of the project. We would prefer to extend our sincere thanks to Dr. Ganesh D B, Principal, and Director, J.I.T, Davanagere, for his moral support and encouragement throughout the project.

    Figure 6: White board system

    When the switch is ON the duster moves horizontally through motor mechanism and erases the whiteboard with the help of a duster attached to it.


Based on the results of the tests performed , it can be concluded that, when the teacher enters the classroom, they enter the password by using a keypad, then the faculty name, subject name, and time of subject taken are displayed on the LCD. And also display Enters the total student count. After they take attendance lectures enter the number in the keypad then this data will be updated to the higher authority using the IoT system.

The automatic whiteboard cleaning machine was designed and engineered using a low-cost and easy user interface. This machine can be used in classrooms to help teachers keep their whiteboards clean.

The lights and fans can work well. The lights and fan can turn on automatically when the sensor detects a person and the lights and fans can also turn off automatically when the sensor detects non is there in the classroom.


Although one sentence is not enough, we would like to thank Almighty God for blessing us with his grace and for taking our efforts to a successful climax. We would prefer to express our gratitude to our mentor Ms. Anusha K, Assistant professor, Department of ECE, JIT, Davanagere, for her valuable guidance and ongoing encouragement and assistance in the project work. We would wish to express our gratitude to
