Here is a working video of project shared by Anudeep: Its urgent plzz reply Asap! This project has 2 sensors. Finally, the system was deployed and tested in real world situations to enumerate its efficiency. Caution: Be extremely cautious when using 230V mains supply. Here is two functions for enter and exit. So visitors in the room are counted up by Sensor1 and Sensor2 counts visitors going out of room. Then Microcontroller decrements the count.
If zero condition is true then arduino turn off the bulb by deactivating the relay through transistor. Human efforts to count the number of person is eliminated. This project is divided into four parts: sensors, controller, counter display and gate. It is very interesting project for hobbyists and students for fun as well as learning. This circuit proves to be helpful. A Project on Automatic Room Light Controller With Bi-directional Visitor Counter By Kushal Sarkar, Roll No. Lower the context switches, average waiting and turnaround times; higher the efficiency of an operating system and thus better embedded system.
But i have a question. This paper describes the development and implementation of real time bidirectional visitor counter along with automatic room light controller. I would like to thank Prof. It is an active low device, which means it gives low output when it receives the Infrared rays. So, our goal is to reduce running time of an algorithm along with efficiency constraints such as context switches, average waiting and turnaround times.
This has fueled my enthusiasm even further and encouraged me to boldly step into what was a totally dark and unexplored expanse before me. This process will make the microcontroller to understand that a person is trying to leave the room and hence, it will decrement the count of visitors. Secondly is it possible if we remove the transformer and directly supply 9volts to the circuit? Relay: We have used 12 volt relay. Here we used +12V and +5V dc power supply. The total number of persons inside the room is also displayed on the seven segment displays.
Answer: If there is no gap between two persons, then Microcontroller will sense that only 1 person has entered into room. If you find any difficulty in working with relay, check out this tutorial on to learn more about operating relay with Arduino. Can u suggest any other sensors which will detect only human being or human body? Many times we leave the room and hall without switching off lights and fans, thus electricity is wasted. To the complete material on this particular topic above click Do you want our Bank Accounts Details? The sensor would observe an interruption and provide an input to the controller which would run the counter increment or decrement depending on entering or exiting of the person. This paper reports on a system that can save electricity. It can control multiple devices.
To make custom components refer the help section of the software. Project will display actual number of persons inside the room. Today we are here with automatic room light controller project with bidirectional visitor counter by using Arduino Uno. All these sensors data is collected by the microcontroller and is processed for meeting certain conditions. Zero condition means no one in the room.
I am working over this project as my minor project!! And also check for zero condition. Please Like, Share, Comment and Subscribe Youtube: Twitter: Facebook: Google Plus:. All the components required are readily available in the market and the circuit is easy to build. There we got over first trouble. Automatic Room light Controller project can also be used in our home because many times we come out of our bedroom or any other room and we forgot to turn off the room light.
The in such a way that by the reception of the signal from the sensor-1 it turns on the fans and lights inside the room. To avoid this situation, sensors should be placed at the higher level from ground. Hello Sir, Is there anyway to prevent the counter from moving up or down when i place my hand infront of 1 of the sensors constantly? Simultaneously we can vary the speed of the fan sensing the room temperature. As a visitor enters the room, the count is incremented by one and the lights are switched on. And if it is interrupted then the microcontroller will decrement the count. Microtronics Technologies - This project requires power. By using this sensor and its related circuit diagram we can count the persons.
The proposed system keeps track of visitors visiting a room as well as takes over the control of the room lights. In this system, a microcontroller is the central processing unit of this project which is of 89S51 controller from the 8051 family. All we need is to do minor changes to activate this telephone as it works as to become auto dialer circuit. The efficiency of embedded systems mainly depends on the process scheduling policy of operating systems running on them. As soon as visitor count reaches 0 the room light turns off.
Then comparator compares both voltages and generates a digital signal at output. Arduino read these signals and send commands to relay driver circuit to drive the relay for light bulb controlling. It is made to unwanted prevent electric power waste in schools, colleges, offices and houses. Lights of the room are switched off only if there is no person inside. If there are more visitor, the microcontroller will keep the light turned on and increments the visitor counter accordingly. Corresponding circuit diagrams are also provided.
