Abstract

Nowadays, the internet has become a vital part of our daily lives and common interface in many electronic devices which have been used to simplify people’s daily lives. The purpose of this project is to develop a low cost classroom’s door that can be controlled through online system. Furthermore, vandalism in our community has become major problem that continues on arise every day. This problem has made the community become uncomfortable because they are unable to use the facility provided, especially in university culture that being provided by the government. By implementing this system at university, the safety level of the classroom can be improved by reducing the risk of vandalism especially during night activities. The Development of Smart Lock for Classroom Using NodeMCU ESP8266 is a system where classroom’s door can be controlled by smartphone application using valid identification and password via WI-FI module. There are two ways of opening the door. Firstly, WI-FI module, Android’s application and solenoid door lock combined to operate door accessibility for the authorized person through online system from outside the classroom. Secondly, PIR sensor as well as magnetic door sensor used to detect movement in the classroom thus opening the door lock by sending a signal to the controller. In this part, the buzzer will functionally ON when the door is open within short amount of time set in the system. This system finds a wide application in areas where physical presence is not always possible
