1. Dual-Voltage Regulator PCB Design Using LM2678-5.0 and TPS5430 Buck ConvertersAs part of my work in power electronics design, I developed a dual-voltage regulator PCB using Altium Designer, based on the LM2678-5.0 and TPS5430 buck converters. The circuit efficiently steps down a common 12V input to a stable 5V output, offering a selectable current capacity of either 5A or 3A through the integration of an SPDT switch. By incorporating key components such as inductors, Schottky diodes, and capacitors, the design ensures efficient power delivery with minimal ripple, making it ideal for high-performance applications. This project showcases my proficiency in PCB design, embedded systems, and power management solutions.2. GPS Data Logger Using ATmega328P MicrocontrollerI also designed a GPS data logger utilizing the ATmega328P 8-bit microcontroller, aimed at accurately capturing and efficiently storing GPS data. The ATmega328P was selected for its simplicity and reliability in data logging applications. Power regulation was achieved using an LM7805 voltage regulator, along with capacitors to smooth out voltage variations, ensuring stable power delivery to sensitive components. The entire design was completed using Altium Designer, which enabled precise component placement and optimal routing to ensure system reliability.

I have developed a smart water meter using two ESP32 microcontrollers, five sensors (TDS meter, PH sensor, temperature sensor, water flow meter, and water pressure sensor), two LoRa modules, and one OLED display.The project is divided into two parts: data transmission and data reception.In the transmitter node, one ESP32 is connected to the five sensors through its analog or digital pins. Additionally, a LoRa module is connected to the ESP32 for transmitting sensor data. Communication between the ESP32 and the LoRa module is established via the SPI protocol.In the receiver node, another ESP32 is connected to a second LoRa module for receiving data. This ESP32 is also connected to an OLED display for visualizing the data, with communication between the ESP32 and the OLED display established via the I2C protocol.The main aim of this device is to measure the quality of the water and the quantity flowing through the pipeline.
