System automation has become the most popular field due to its efficiency, comfort and ease in operation of many electronic devices from remote locations. This paper focuses on Office Automation system, where user can control electronic devices like lights and fans and also can securely handle very important office data remotely using a smart phone. This paper aims the design and implementation of Internet of Things (IoT) based office automation system using NodeMCU ESP8266 Wi-Fi module and by developing this system we are able to control office appliances through any smart phones in real time. The control commands are instructed by the user’s smart phones. IFTTT Google Assistant is used to give the voice control commands. The system’s hardware consists of NodeMCU, sensors, Relay driver module and Power supply. The software requirements for this project are Arduino IDE, Blynk App and IFTTT. Internet of Things application is implemented using NodeMCU which is a credit-card sized computer aimed at providing a computer operation from anywhere. It can securely handle some important and confidential office data which is stored on office computer and sometimes required to handle using smartphones. Cloud computing services are used which gives host the data of owner on the server and authorized users can access the data of the servers. The smart mobile is joined to the computer system with the NodeMCU using the IP address via Wi-Fi. Wireless applications using Wi-Fi is user-friendly, improves the efficiency of the system, and it successfully overcomes the drawbacks in the Bluetooth and ZIGBEE technology.
