Automatic Room Light Controller Circuit and Applications

automatic light controller with visitor counter

Relay acts as a switch. If the second sensor is not interrupted within 5 seconds then the waiting period gets over and action is cancelled. Visit: for more info Two infrared sensors are used to count the number of persons inside the room. The relay is used to operate the external solenoid forming part of a locking device or for operating any other electrical devices. It is an active low device, which means it gives low output when it receives the Infrared rays. Today we are here with automatic room light controller project with bidirectional visitor counter by using Arduino Uno. Question: Hi sir, this project is almost well for us but i want to know about disadvantages for this project.

By using this circuit and proper power supply we can implement various applications such as fans, tube lights etc. Power Supply:Here we used +12V and +5V dc power supply. Complex functions like internal combustion controls are often handled with multi-dimensional tables. For another example, look at a small computer printer. Chapter 3: Materials and Methodology 10 i. In this block mainly we are using the transistor and the relays.

Darlington pair: It is used to increase the current gain. Then Microcontroller decrements the count. This has fueled my enthusiasm even further and encouraged me to boldly step into what was a totally dark and unexplored expanse before me. Counting the visitors helps to maximize the efficiency and effectiveness of employees, floor area and sales potential of an organization. Firmware is usually developed and tested too much stricter requirements than is general-purpose software, which can usually be easily restarted if a problem occurs. This project is divided in four parts: sensors, controller, counter display and gate.

After receiving the control signals from the transmitter section, the Zigbee receiver sends these signals to the microcontroller. Question: when a cat or any other animals comes across the ir sensor , will light remain on or off? You can download project abstract and seminar presentation also from the website. Automatic room light controller On the other hand, the energy resources like petroleum, coal, natural gas, uranium and propane are called non -renewable resources, because their supplies are limited. Aritra Acharyya, Assistant Professor, Dept. And if any person leaves the room then second receiver will cut and then first receiver will cut.

Automatic Light Controller with Two Unidirectional Guest Counters Muhammad Shaheed D. And Relay driver transistor at digital pin 2. 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. Relay Driver Circuit:- This block has the potential to drive the various controlled devices. A monostable multivibrator is a timing circuit that changes state once triggered, but returns to its original state after a certain time delay.

And the value shouldn't go negative as there is condition for that in the code, please check. So if any animal crosses the sensor then the visitor counter will be incremented or decremented depending on the direction and then lights will be turned on if count is greater than zero. This function is implemented using a pair of Infrared sensors. The objective of this project is to make a controller based model to count number of persons visiting particular room and accordingly light up the room. Applications of the project: 1.

When number of persons inside the room is zero, lights inside the room is turned off using a relay interface. I am working over this project as my minor project!! To the complete material on this particular topic above click Do you want our Bank Accounts Details? Frequencies between 30 kHz and 60 kHz are commonly used in consumer electronics. Answer: In such cases the counter will not be incremented. What is the use of buzzer in this project… Answer: Buzzer will be turned on when maximum limit of person count has reached. Automatic Room Light Control When we enter a room, as a habitual tendency, we often search for a switch to turn the light on, and if we are new to the room, we often find it difficult to locate the switch.

Embedded systems technologies are usually fairly expensive due to the necessary development time and built in efficiencies, but they are also highly valued in specific industries. The microcontroller does the above job. Automatic Room Light controller section — Microcontroller turns on the Room Light when person count is greater than or equal to one. The matter embodies in thesis is original and has not been submitted for the award of any other degree. We can send this data to a remote location using mobile or internet.

B technical University, is a record of the candidate own work carried out by him under my own supervision. The purpose of these three blocks is to detect the presence of the modulation frequency. Nowadays, human has become too busy and he is unable to find time even to switch the lights wherever not necessary. A Project on Automatic Room Light Controller With Bi-directional Visitor Counter By Kushal Sarkar, Roll No. The objective of this project is to make a controller based model to count number of persons visiting particular room and accordingly light up the room.

What can be the problem? It can be used to count the number of. And the room light is controlled through this relay. I am doing a solar automatic lighting control system for a house. The sketch would be very easy to write however you are going to learn how to do it. This circuit, in effect, produces a pulse at pin 3 whose width t is just the product of R1 and C1, i. In addition to the lights, fan loads can also be controlled in this project based on the temperature inside the room.
