hi,
i am an electronics engineer and i have a great experience of circuit designing and microcontroller based embedded system designing. i can design this project with efficient output response according to your requirements. this project requires a microcontroller, infrared modules and a module for communication between server and the device. the two ir-modules pairs e.g. (Tx-LEDs & Rx-LEDs) will setup a two ir- beams in parallel and the decesion of in or out for a person will be made on the first cut occur or the which beam cut first. microcontroller will count the the number of in and out and then store them into its memory. the stored data can be send to server with wireless and so many techniques.
for further details please contact me.
Thanks,
Rizwan
