We are leaders in the market for providing best range of Employee Log System Using PC and Easy Message Sending Using PC
Manual operation of maintaining the employee log is a mundane task prone to human errors. This project Employee log system using PC and RFID is the best solution for this problem. Radio Frequency Identification (RFID) Card Readers provide a low-cost solution to read passive RFID transponder tags up to 2 inches away. The RFID Card Readers can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics navigation, inventory tracking, payment systems, and car immobilization. The RFID card reader read the RFID tag in range and outputs unique identification code of the tag at baud rate of 9600. The data from RFID reader can be interfaced to be read by microcontroller or PC. The project is designed in such a way that the controller will be interfaced to the RFID reader through a line driver IC max232 for serial communication. On the other hand, the controller will also be interfaced to the PC serially. Serial communication is often used either to control or to receive data from an embedded microprocessor. Serial communication is a form of I/O in which the bits of a byte being transferred appear one after the other in a timed sequence on a single wire. Each employee will be sanctioned with a unique RFID card. Whenever an RFID card is swiped over the Reader, it gets the card information and sends to the microcontroller serially. So the controller receives the data and transmits it to the PC, as per the code logic. C# application in PC always interact with serial port and it maintain the data base along with corresponding card details. So based on the received data the application can update the employee/student log. As per the design of the application , we can check the employee logs on the required dates at any time. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
The project is aimed to design a system using which we can send the messages to the mobile by using PC and a GSM modem, without internet connection to the PC. GSM Modem can accept any GSM network operator SIM card and act just like a mobile phone with its own unique phone number. Advantage of using this modem will be that you can use its RS232 port to communicate and develop embedded applications. Applications like SMS Control, data transfer, remote control and logging can be developed easily. The modem can either be connected to PC serial port directly or to any microcontroller. The project is designed in such a way that the controller will be interfaced to the PC, as well as to the GSM modem through a line driver IC max232 for serial communication. Serial communication is often used either to control or to receive data from an embedded microprocessor. Serial communication is a form of I/O in which the bits of a byte being transferred appear one after the other in a timed sequence on a single wire. The front end application will be developed on C# .NET platform for the visual effects so that the application can be easily accessed. The application will be designed in such a way that it contains a text box in which we can enter the required text and as the application always interact with the serial port it sends that text to the PC serially and then the controller sends it to the GSM modem in an SMS format as per the code logic. So that the mobile with the preprogrammed number will receive that particular message through GSM modem. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
