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.     Micro Controller : AT89S52 Crystal : 11.0592 MHz Lcd : HD44780 Pc Rfid Reader Max232 Software Requirements Keil Proteus Uc Flash C# Embedded C

SmartM is small and reliable solution for your next IoT project. Keeping the latest trends in mind new data transfer method is introduced. Now instead of sending data to server via traditional methods like TCP/UDP, SmartM can send data directly to your HTTP server or web service and in a very friendly format known as JSON (JavaScript Object Notation). Since JSON is one of the common data exchange method available in all web technologies, so implementing a receiving frontend for SmartM will be much easier than writing a TCP listener. This will also help lower down your web server requirements and hence the overall cost of implementation.  About JSON JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate JSON data. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. Why JSON? The reason for introducing JSON to SmartM was to ease and expedite front end development for it. Since most of the web developers are very much familiar with formats like JSON and ample amount of support available on web. Moreover, all web development platforms support JSON and its parsing. This is the reason JSON has become common data exchange format between IoT devices and web services.   SmartM can work in two different modes of operation A. RS485 Gateway B. Transparent Device can be configured to work in any mode using “appmode” command. Once configured device must reboot for mode change to take effect. RS485 Gateway Mode: In this mode device collects data periodically from connected slaves based on the register configuration file (reginfo) loaded in the device. Device supports a maximum of 10 slaves for a reliable operation. The transmission rate can be configured for this mode. When connecting different types of slaves, please make sure the MODBUS communication parameters are same for all the devices. E.g. user cannot connect a device that communicates at 9600 baud rate with another device running at 115200. Please refer to section Register Information File section for more information on reginfo file format. Transparent Mode: In this mode of operation, device creates a transparent channel between server and external MODBUS. Anything sent from the server is passed directly without any modification over MODBUS and vice-versa. This mode is mainly useful where user need to take exclusive access of MODBUS or devices on MODBUS. In transparent mode, device makes a TCP socket connection to server and on successful connect device sends its device ID in format “UID=”. After this any data sent to the device will be passed on to MODBUS slave and any data (raw) coming from MODBUS slave will be sent back to server. Feature are listed below : ·              Runtime configurable register set ·              Multi slave support ·              JSON support ·              Secure data transfer via HTTPS ·              Offline data storage in case of server unavailability ·              Bluetooth support for configuration and easy installation ·              Remote configuration via SMS and server ·              OTA Upgrades ·              Expandable using LUA scripting ·              Post data processing using LUA script ·              Switch between gateway and transparent mode any time.   ·              MODBUS protocol selection RTU or ASCII
