Secure Warehouse with Automatic Stock Calculation

Better Inventory management is the most difficult task in case of big warehouse/go-downs which may have hundreds or lacs of items stored in time. Sometimes it may also include valuable goods like costly mobiles, diamonds, laptops etc. so there may be a chance of theft. While due to number of items it is difficult to carry out stock calculation frequently and reliably as it is human driven process. Hence a system is required which calculates the number and type of items and that gets displayed on screen. It may also be displayed which item has been removed or stolen as soon as it goes away. Hence it also provides security. The system includes RFID transmitters which are to be mounted on each item. RFID transmitter transmits the unique code continuously and it is received by the RFID receiver. It decodes the unique code and generates the binary pattern which is given to the 8051 microcontroller. Microcontroller calculates which kind of stock it is and update its record and displays it on LCD. By this Automatic stock calculation it reduces human effort and error as well as it increases the speed and security of goods. For better security purpose GSM Modem and PIR sensor are used.
