The objective of this paper is to design an efficient room automation system in POLIMAS to control and automatize lighting, fan and air-condition.. This system will overcome human mistakes where the students or staffs forget to switch off the appliances in classroom or laboratories, and effectively reduce the cost of operation and power consumption of the buildings. Room Automation involves the automation and controlling the electrical appliances. The system will monitors electrical parameters of room appliance such as temperature, humidity and ambient light. The factors like temperature and light can have significant effects on the productivity of office workers as well as students. Thus, classrooms, laboratories and staff offices can be equipped with super sensors featuring temperature and light monitors. Besides, it helps in reducing power consumption by monitoring the environment condition and controlling the appliances as well as conservation of energy in the campus. Furthermore, it provides simple and cost effective to the institution. The system uses Arduino ESP8266 NodeMCU platform as the IoT enddevice connecting to various sensors and actuators to the platform via Wi-Fi channel. By using Wi-Fi connectivity, the hardware integrates with software application to control, monitoring and analysis. A sequence testing is conducted to determine the connectivity and integration of hardware and software. The performance of each sensor was performed to measure the accuracy. As a result, PIR sensors are able to detect general movement in effective range of about 10 meters. Moreover, the DHT temperature sensor in range of 5 meters away from air-condition is able to read the present room temperature and send command to the air-condition adjusting the air- condition’s set temperature similar to the air-condition’s remote. Thus, by implementing this system, not only the electrical appliances in a room more manageable and under control but also able to reduce the operational cost and improve environmental protection.
