Abstract - Nowadays, office automation is becoming an important and inspiring field that has shattered over past few years. The current advances in electronics and communications Technologies have made office area more convenient, efficient and more secure. The office automation refers to the monitoring and control of office appliances by utilizing information technologies .With the rapid rise in the use and potential of internet, it can be possible to handle, monitor and control different electrical devices in office areas. Embedded systems can be interfaced with internet to accomplish the automation. The project report presents office automation system using internet of things technology. The smart office automation system is implemented in existing office area without making any major changes in the infrastructure. In recent years the popularity of office automation has been increasing due to the low cost and the simplicity can be achieved via use of smart phone. In this context the internet of things concept has been tied with the office automation system Key Words: IoT, Office Automation, RFID Reader, node MCU, etc. 1. INTRODUCTION
in the office and also to leave from office. The tome of entry and exit of employee will be sent to the cloud using the IoT. Here we have used Atmega328 microcontroller to process all the operation. To transmit the data over internet we have used ESP8266 Wi-Fi module. We have used Thingspeak website to upload the data over cloud. Also we are displaying who has scanned RFID card with the help of LCD display 1.1 The Concept of IoT The Internet of Things (IoT) is regarded as a technology and economic wave in the global information industry after the Internet. The IoT is an intelligent network which connects all things to the Internet for the purpose of exchanging information and communicating through the information sensing devices in accordance with agreed protocols. It achieves the goal of intelligent identifying, locating, tracking, monitoring, and managing things. It is an extension and expansion of Internet-based network, which expands the communication from human and human to human and things or things and things. In the IoT paradigm, many objects surrounding us will be connected into networks in one form or another. 2. SYSTEM ARCHITECTURE
There are basically two parts of our project. One is office load control using IoT and another is to take attendance of employee by RFID and store it on the cloud using IoT. It is quite difficult for individual office owners to operate one or more that one office and keep track of each office appliances individually. At such time we need an online solution for physical office appliances control. Here we propose use of IoT technology for office appliance automation. This allows owner to control his/her office appliances through the internet using an easy to use android app. For this system demonstration our system uses a Node MCU microcontroller for the purpose. Inbuilt Wi-Fi modem is used for receiving commands over the internet. We use 3 loads to demonstrate as office loads. The Wi-Fi module receives user commands over the internet. This information is then passed on to the microcontroller. The microcontroller now processes this data and switches the loads through relays. Thus office automation system allows user to control his office remotely using IOT technology.
Many types of RFID exist, but at the highest level, we can divide RFID devices into two classes: active and passive. Active tags require a power source they’re either connected to a powered infrastructure or use energy stored in an integrated battery. In the latter case, a tag’s lifetime is limited by the stored energy, balanced against the number of read operations the device must undergo. One example of an active tag is the transponder attached to an aircraft that identifies its national origin. Another example is a Low Jack device attached to a car, which incorporates cellular technology and a GPS to locate the car if stolen. However, batteries make the cost, size, and life-time of active tags impractical for the retail trade. Passive RFID is of interest because the tags don’t require batteries or maintenance. The tags also have an indefinite operational life and are small enough to fit into a practical adhesive label. A passive tag consists of three parts: an antenna, a semiconductor chip attached to the antenna, and some form of encapsulation.
Secondly the RFID system, in which we have used the RFID reader to read the RFID cards which has given to the employees. The employees have to scan RFID cards to enter © 2017, IRJET
