Nazmul Department of Electrical and Electronic Engineering, Brac University NodeMCU Relay driver BJT Power supply Step-Up transformer Voltage regulator Internet of Things Artificial intelligence This thesis is submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Electrical and Electronic Engineering, 2021. Cataloged from PDF version of thesis. Includes bibliographical references (pages 42-44). A voltage stabilizer is a device that detects and corrects abnormal voltage levels in order to create a sufficiently steady output where the load is attached. The goal of this project is to build and construct an automated high-performance voltage stabilizer that can identify and adjust incorrect voltage levels to provide a sufficiently steady output as well as monitoring the output voltage wirelessly through NodeMCU microcontroller unit and Blynk mobile application. The system is comprised of five interdependent architectural designs: power supply, voltage regulator, monitoring circuit (NodeMCU), and step up transformer, which provides the needed signal when activated by a relay driver to illuminate the bulb. The relay contacts are suitably integrated to the transformer taps to carry out the aforementioned operations in accordance with the directions provided by the BJT (Bipolar Junction Transistor) output. The proposed circuit works well and the results are good. When installed, the relay trips whenever the input voltage exceeds 250 volts, lowering the output voltage to 220 volts and holding it there constantly. When the voltage is fixed at 220 volts, the relay de-energize while pulling the voltage to approximately 240 volts and retaining the difference when the voltage falls further. The preceding operation maintains the appliance's output voltage between 220 volts constantly, with variations ranging from 140 to 250 volts.
