Whenever the station arrives the train stops automatically. Reset button will reset the microcontroller. And this pulse will be given to microcontroller for further processing.


The Power-down mode saves the RAM con- tents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset. Hi khushboo thakare, we can implement computer interfacing or GSM modem interfacing with this project. Hi Naveen, Two transmitters should have sufficient distance between each other so that they will not interfere with each other.

The data register stores analog-to-digital converter ADCwhich converts the analog the data to be displayed on the LCD. Proposed system architecture is shown in Figure 1. Is it possible that in entry operation, the RFID will count and in the exit operation, the infrared will count? We have not used any separate IC for the counting. AT 89S52 micro-controller 4.


Hi naga akhil es, It can not detect this situation. This circuit proves to be helpful.

Because when there is nobody inside the room then lights are automatically turned off. The LM is a highly stable device for generating accurate time delays or oscillation. Some shields interruption, the system identifies the entry and exit visifor the visitor.

The cost of this technology is very economical.

So the relay light will be turned on when there is darkness. Any IR sensor module should auomatic here, please set the proper sensitivity of sensor by rotating the potentiometer on wifh. You can keep them at 4 feet from ground. We have used Infra-Red transmitters. Hi Raj, yes there will be a program HEX code downloaded into the controller. If you look at the circuit diagram, it already has v AC bulb connected through the Relay.

These details are mentioned in the project report. It is used to increase the current gain. But please send details of wigh customized requirement to our email id.

Here is two functions for enter and exit. We have used to 2 pairs of Transmitter and receiver. Bidirectional person counter project can be used in Cinema halls, multiplex, malls as well as in temples to count wit number of person entering inside.


The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory pro- grammar. Can you please send me the altered program which worked for you. We started testing the circuit from the power supply. LDR will detect the sunlight. Is the programme is alredy dumped by you?

Automatic Room light Controller & Person Counter

Sir, how will the code change accordingly if I use microcontroller in place of aurdino board. Your email address will not be published. Zero condition means no one in the room. Try around some codes and share with us.

Automatic Room light Controller with Visitor Counter

Used for audio B. But then all these devices will be turned on or off at the same time. Because of this appropriate device is selected and it do its allotted function. If there is enough sunlight in the room which means it is a daytime then the relay will not be turned on even if the person count is greater than zero.
