Implementation of room automation with cloud based monitoring system

As the time spent inside the office and comfort level is rising, the office room is alter for automatic control and observation of various parameters. Internet of things (IoT) system proposed in this paper based on arm controller and Thingspeak cloud provide solution for automatic control of office room appliances such as light, fan, AC by considering human comfort. Various office room parameters like temperature, light intensity, connected load, energy consumption, voltage and current consumption can also be monitored and analyzed from anywhere over the internet. Electrical appliances will turn on only when there is presence detected by the PIR sensors. Workable room environment such as light intensity and room temperature are maintained and monitored by using lux sensor and temperature sensor respectively. The room automation system based on IoT consist of sensors (temperature sensor, lux sensor), arm controller board, multifunction energy meter, ESP8266 Wi-Fi module and Wi-Fi router.
