Wearable Heart Rate Monitor
Designed and prototyped a wearable heart rate monitoring device using a MAX30102 optical pulse sensor, an Arduino Uno, and a 433 MHz RF transmitter/receiver to acquire, process, and wirelessly transmit real-time heart rate data. The system converts raw PPG signals into BPM values and provides immediate visual feedback via an LED indicator, with emphasis on power efficiency, signal integrity, and user-centric device design.

Process
- •Defined requirements and selected the MAX30102, Arduino Uno, and 433 MHz RF modules for non-invasive heart rate sensing and wireless communication.
- •Integrated sensor, RF module, LED indicator, and battery supply to enable reliable signal acquisition and data transmission.
- •Developed firmware to process PPG signals, compute BPM, and drive real-time LED feedback with emphasis on power efficiency.
- •Assembled and tested a wrist-mounted prototype during rest and physical activity to validate responsiveness.
