yes.I want to know about, how the automatic room light controller works.

The project of "Digital visitor counter" is based on the interconnection of some components like sensors, motors, etc. With the Arduino micro-controller. This counter can count people in both directions. This circuit can be used to count the number of people entering a hall / mall / home / office at the entrance door and can count the number of people leaving the hall decreasing the count at the same door or exit door and Depends on the sensor Placement in the shopping centre / room. It can also be used on the doors of parking areas and other public places.
This project is divided into four parts: sensors, controller, counter and door. The sensor would observe an interrupt and provide an input to the controller that would execute the counter increment or decrement depending on the person's input or output. And the account is displayed on a 16x2 LCD via the controller.
When someone enters the room, the IR sensor will be interrupted by the object, then the other sensor will not work because we have added a delay for a while.
"Automatic Room Light Controller with Visitor Counter Using Micro-controller" is a reliable circuit that assumes the task of controlling the lights of the room, thus we counting the number of people / visitors in the room very accurately. When someone enters the room, then the counter increases by one and the light in the room will turn on and when someone leaves the room, then the counter is decremented by one. The light will just turn off until all the people in the room come out. The total number of people in the room is also displayed on the seven-segment screens.
The micro-controller does the previous work. It receives the signals from the sensors, and this signal is operated under the control of the software that is stored in ROM. The micro-controller continuously monitors IR sensors, when any object passes through the 555 timer generates a pulse and interrupt controller. So visitors in the room are counted by Sensor1 and Sensor2 counts to visitors coming out of the room. As soon as the visitor count reaches 0, the room light goes out.
