interfacing 2 ir modules gsm module & lcd display with 8051

[Hari Prasad Reddy]

I want to know that is it possible to interfacing 2 ir modules gsm module & lcd display with 8051 ?

If yes the how it could be?

I want to interface these without the need of PC. My idea is to detect speed of vehicle and send a message to a particular number if the vehicle exceeds speed limit.

Please help me.

Nice project. You can connect the IR sensor via an ADC to the digital pins of the controller. The LCD can be directly connected to the digital pins. The GSM module can be connected to the UART pins.

Thank You sir. Can you represent it with a block diagram/ pin representation please. My project work depends on your reply.

Hi,

sorry for the delayed response. here is the block diagram. One IR module is connected via ADC enabling analog read, while the other is directly connected to a digital pin only providing digital read.

May I know the purpose of two IR modules?

Thanks again sir.

When an object goes between these IR’s, using distance/time, we can calculate the speed of object interrupt & timer in8051.

Can you give me the pin configuration please?

[AJISH ALFRED]

I’ll surely help you with that, before that tell me the part number of the gsm, lcd and ir modules which you are using

[Hari Prasad Reddy]

Sorry for late reply.

I can’t understand ‘part number’ sir.

SIM300 GSM Module, IR LED & Photo Diode, 16×2 LCD Screen are being used.

GSM Module & IR modules are connecting to port3 & LCD to Ports2&0.

refer the project from this site for gsm and lcd interfacing with 8051

engineersgarage.com/microcontroller/8051projects/interfacing-gsm-8051-microcontroller-circuit-code

don’t forget to set the ports accordingly.

if ir modules have digital output, it can be simply connected to any of the digita io pin
