In the kit SMS based Mesh management system here, the system is designed to minimize the wastage of foods in mesh/ hotel etc. It is suitable for those places, like mesh or hotel etc where the people pay monthly for their flooding. If on any day the person doesn’t want to go to the mesh, then he just has to send a SMS. At the mesh station, our system will be installed; it will automatically deduct the total count for the day. There are two main advantages of using this type of system: first of all the food wastage will be less and secondly the person has not to pay for the day.
In the kit SMS based Mesh Management system there is a GSM modem connected with the microcontroller, which works on the UART port. Any SMS after being received by the GSM modem is forwarded to the microcontroller. The controller looks for the proper format of the SMS, if matching is not there, then the SMS is discarded by it. Hence, there is security also for unauthorized access. A dot matrix LCD is there to display the proper count. There are two modes of operations for the system: automatic mode and broadcast mode. In automatic mode it keeps listening for the SMS and in broadcast mode, it sends the message to all registered users and then waits for their response.
