Abstract: The Automatic counting and MSG sending using GSM system is most widely used in industries. Automatic bag counting offers extreme advantages over traditional off determining what product has been received at the godown. In this system also detect defected bags. And defected bag is automatically removed by using shaft. Manually it is not possible to find defected bags so this is good advantage to this system. If weight of bag is less than the considered weight then weight sensor sense it and defected bag is found and immediately shaft will remove that defected bags and after detection bag will automatically counted by laser sensor. Manual counting is very time consuming process. The basic purpose of automatic counting and MSG sending using GSM module system is bags are counted automatically and MSG will be send to mobile of supervisor in specific period. It is most efficient system for counting bags. The PIC16F877 controller provides counting product automatically and also help to find defected bags accurately. The laser sensor makes the system efficient.
