Water Level Monitoring and Control PCB
Designed a custom ESP32-based PCB to monitor water level and control pump or valve behavior, with LCD output, buzzer, LEDs, and relay integration for operational feedback.
Portfolio
Embedded Projects Spanning Healthcare, Automation, Robotics, and Smart Control.
These examples are based on the public project and profile details available from my freelance profiles. They show the range of systems I build, from PCB-level control boards to connected monitoring devices.
IoT-Based ECG Monitoring System
Developed a Real-time ECG monitoring setup using ESP32 and AD8232 to capture bio-signals and support remote observation and future connected-health workflows.
Medication Monitoring System
I designed and implemented a Medication Monitoring System (Smart Pill Box) to help elderly people and patients adhere to their medication schedules reliably and safely. The system includes an Arduino Uno WiFi microcontroller, integrated sensors to detect pill removal, Servo motors for pill dispensing, and a user-friendly interface for real-time monitoring and alerts.
Hand Gesture Controlled Car
Combined a glove-mounted accelerometer, Arduino Pro Mini, RF communication, L298N motor driving, and ultrasonic sensing to create a gesture-based assistive control vehicle.
Automated Solar Panel Cleaner System
I designed and implemented an Automated Solar Panel Cleaner System to improve solar panel efficiency by removing dust and debris without manual intervention. The system is built using an Arduino Uno, DC motors, and an L298N motor driver, and is controlled remotely using an IR transceiver.
Smart Irrigation System
I designed and implemented a Smart Irrigation System that automates watering based on real-time soil moisture levels, reducing water waste and improving irrigation efficiency.
