Abstract
Computer laboratory plays the role of key elements with high interest for different categories of populations. Event of fire, smoke, heat, and water leakage when occurs could cause a big loss for business continuity. This paper presents a developed system for the internet of things (IoT) based smart fan controller and fire prevention in the computer laboratory. The aim was to develop an automated computer laboratory that would control and monitor the computer laboratory environment from the incident of fire, heat, smoke, and water leakage. The system was created using three nodes and a single database. The first node used a flame sensor which detects fire and activates a fire extinguisher automatically. The second node used a digital humidity and temperature sensor (DHT), along with an ultrasonic sensor, which was used to manage a fan controller and activate the controller when the temperature is high and a person is present. Thirdly, smoke and water sensors were used to detect the presence of smoke and water leakage. Microcontrollers, access points, and software are used to accomplish the development of this system. Different actions of warning users were done. Triggering buzzers and sending emails were done whereas fire, smoke, and water leakage are detected. The email was also sent to the users registered in the system when there was a temperature of more than 25.
