But instead of count one it count continuous i think so their is problem in programm plz someone upload correct programm other than it it has no problem reply must Hello Sir, Great project. ???? I am doing a solar automatic lighting control system for a house. I connected my sensors to P3. To the complete material on this particular topic above click Do you want our Bank Accounts Details? The relay requires 12 volts at a current of around 100ma, which cannot provide by the microcontroller. 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. There we got over first trouble. For astable operation as an oscillator, the free running frequency and duty cycle are accurately controlled with two external resistors and one capacitor.
Mainly this block diagram consist of the following essential blocks. Try around some codes and share with us. The transformer works at 240V but here in Canada we have 120V so do we change the transformer to 120v if yes what transformer we need? And if there insufficient sunlight in the room then only the relay will be turned on so as to turn on the bulb. The various functions of Microcontroller are like: I. This circuit, in effect, produces a pulse at pin 3 whose width t is just the product of R1 and C1, i. By using this sensor and its related circuit diagram we can count the persons.
This person count will be incremented if somebody enters in the room and at that time lights are turned on. The microcontroller does the above job. This section will display the counted number of people and light status when no one will in the room. Such a portable security system is described here. Question: Does it works for same entry ,exit door. That is easy for me but when I turn toward the main circuit, there are many problems and issues related to it, which are I faced, like component selection, which components is better than other and its feature and cost wise also, then refer the data books and other materials related to its.
This process is used to prevent automated spam bots. We are hoped that our project would prove helpful to common persons, also in helpful in world that develops the new technology day per day. I have checked all the circuitry, its fine. At last but not the least I want to thank my friends who appreciated me for my work and motivated me and finally to God who made all the things possible. This is a bidirectional visitor counter.
In the website you have given a chart showing the placement of the circuit, in that picture the transmitter1 and receiver2 is on one side of the frame and vice versa. We have used Infra-Red transmitters. Applications of the project: 1. 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. 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. To avoid this situation, sensors should be placed at the higher level from ground.
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. The microcontroller does the above job. Bidirectional person counter project can be used in Cinema halls, multiplex, malls as well as in temples to count the number of person entering inside. A monostable multivibrator is a timing circuit that changes state once triggered, but returns to its original state after a certain time delay. It differs from a submersible, which has more limited underwater capability.
The total number of persons inside the room is also displayed on the seven segment displays. Relay: We have used 12 volt relay. This is to give some presentations on projector or big screens. And Relay driver transistor at digital pin 2. Such automation is very useful in certain areas like energy consumption, reducing human efforts, improving standard of living etc. And Relay driver transistor at digital pin 2.
I am working over this project as my minor project!! Do you have any question or any feedback about this project? Hope you help me with the details Hi, You can install the sensors on either side of the wall where the door opens not on the door. There is a waiting period of 5 seconds. Thus whenever the intruder enters to the area, it activates the sensor circuit of either sound activation or infrared light beam obstruction circuit, the redial circuit become active and give a ring tone to the receiving end. Nowadays the wastage of electricity has become a routine thing for us, and the problem has become frequent at homes, schools, and colleges and even in industries.
