BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Nowadays concept of smart classes is widely used in educational institutions for the better understanding of students. The smart classroom has a revolutionary impact on the conventional teaching methods. Now the complex diagrams (e.g. in biotechnology) representation can be more effectively visualized by the students. Also, different views of the mechanical structures of diagrams can be conveniently shown to the students. However, with the smart classroom introduction in the institutions more electrical and electronic devices are being used in the educational institutions.
[0004] These devices are very much power hungry and consumes lot of electrical power. Sometimes the electrical devices are fully operational even if a number of student present are very less than the complete capacity of the classroom. This leads to a waste of electrical resources. In order to take care of such loses one has to manually keep track of every think in the class room. The electrical appliances can be turned off/on manually if the classroom is not completely occupied. This is very tedious and difficult for a person to always keep track of the strength of students/people in the classroom. Sometimes, the person keeping the track of electrical devices usage can compromise the ambient conditions of the classroom in wake of saving electricity. This can lead to a unpleasant and unhealthy ambient conditions inside the classroom.
[0005] There is, therefore, a need of an automatic system for controlling ambient conditions of the smart classroom based on the number of students/people present inside the classroom without compromising the healthy ambient conditions for studying.

The one or more sensing devices 102 can be configured to sense one or more first parameters of the area of interest, and can correspondingly generate the set of second signals.
[0037] At step 204, the processing unit associated with one or more electrical devices in the area of interest 104 can identify from the set of first signals a number of people present in the area of interest 104. The proposed method can use machine learning techniques for identifying or differentiating people from the captured images or videos of the area of interest 104. A first data associated with the set of first signals can be compared with a pre-stored, in a database, first data containing information associated with non-living objects present in the area of interest in order to identify living objects (can be people) inside the area of interest 104.
[0038] At step 206, the processing unit can transmit a set of actuating signals if value of one or more first parameters corresponding to the identified number of people present in the area of interest is less than a pre-defined threshold value. The value can be identified to be less than a pre-defined threshold value by comparing it to a third data previously stored in the data set. The set of actuating signals can be configured to control one or more electrical parameters of the one or more electrical devices.
[0039] The proposed system for controlling ambient condition of an area of interest 104 can automatically optimize ambient conditions of the area of the interest based on number of people present in the area of interest 104. Also, the system can keep track of the number of people entering or leaving the area of interest 104 and can update the electrical parameters of the electric devices inside the area of interest accordingly.
