Abstract

The ‘Development of IoT Based Portable Ultraviolet Light Emitting Diode Exposure Box’ is mainly designed a smart advance technology to ease and save time of PCB development process. This invention for daily usage of student and lecturers use in Universities. It also can use by small electronic shops that can sell printed circuit board. Microcontroller NodeMCU used in this project for control and monitor the usage of project. NodeMCU is the main brain of the project it will interface between all the input and output devices. The cloud server Blynk application created through the smartphone to control the timer and monitor energy of this project. Purpose of the current monitoring is to prevent damage to the PCB board. The NodeMCU interpret the sensor data and display on LCD display and Blynk application. This project can expose PCB in 45 seconds. Development of IoT based portable ultraviolet light emitting diode is undertakes monitoring the data from current sensor and controlling exposure activities through smartphone. The proposed device decreases the PCB exposure time and has higher efficiency
