About This project involves the design and implementation of a Buck Converter on PCB to efficiently step down DC voltage. It uses switching technology to convert higher input voltage to a lower output voltage with minimal power loss, making it ideal for power regulation in embedded systems.

Wireless Power Transfer (WPT) is a technology that enables the transmission of electrical energy from a power source to an electrical load without the need for physical connectors or wires. This is achieved using electromagnetic fields—typically magnetic resonance or inductive coupling. In our project, we explore a practical implementation of WPT, demonstrating how power can be transmitted wirelessly across a short distance to light up a device such as an LED or power a low-voltage module. The aim is to provide a clean and safe energy transfer method especially useful in applications like electric vehicle charging, medical implants, and mobile device charging.

This project presents a smart embedded system that captures images automatically based on object proximity. It uses an ESP32 microcontroller, an ultrasonic sensor, and a camera module to detect and capture images when an object or person comes within a predefined distance. The ultrasonic sensor continuously monitors the surroundings. When it detects movement or an object within a specific range, it sends a signal to the ESP32. The ESP32 then activates the camera to capture an image. This image can be either stored locally or transmitted for further processing based on the application. Designed for automation and real-time response, this system eliminates the need for manual monitoring and ensures image capture only when necessary. It is particularly useful in applications such as security and surveillance systems, smart doorbells, and restricted area monitoring, where presence detection and automatic imaging are crucial. Built using low-cost and readily available components, this project demonstrates how embedded systems and sensors can be integrated to create efficient and intelligent solutions. The ESP32’s built-in Wi-Fi also allows future integration with IoT platforms for remote access or cloud-based image storage. This prototype reflects real-world applications like those developed by E-Cons Systems, aligning with the company’s focus on embedded vision and intelligent automation.
