A Critical Review of Sensor-based Automatic Room Light Controllers

Abstract

The task of "Automatic Room Light Controller" is based totally on the interfacing of something which includes sensors, cars and plenty of different. This counter may rely on people in each command and this circuit can be used to depend on the form of human beings stepping into a corridor/mall/home/place of work in the front gate and it can reduce congestion in the hall is achieved by strategically placing sensors to monitor the flow of people. This system can be implemented at both the main entrance and exit gates, as well as in parking areas and other public spaces. The project consists of four main components: sensors, a controller, a counter display, and the gate itself. A sensor can also have a look at an interruption and often enter the controller which may additionally implement the counter can be raised or lowered. The character's departure from the scene wastage of strength is one of the primary issues that we're going through. In our homes, university faculties, or business enterprises, we see that fans and lighting fixtures are stored on no matter the fact that there may be no character within the space, area, or pathway. This occurrence arises from either negligence or oversight. To prevent instances where lights are left on unintentionally or due to time constraints, we have devised a project known as the "Automatic room light controller with visitor counter". This project consists of two modules: the "Digital Visitor counters" and the "Automatic room light controller". The fundamental idea driving this project is the implementation of a "Visitor counter" system. This system effectively tracks and tallies the total number of individuals entering a designated space, be it a seminar hall, conference room, or classroom. To achieve this, a series of Infrared sensors are strategically placed. Additionally, an LCD is positioned outside the room, providing real-time updates on the current count of individuals present.
