PulseBot — Alexa Voice Medical Pulse Oximeter

About this project

Build an Alexa voice-controlled medical-grade pulse oximeter using ESP32, MAX30102 sensor, and cloud data logging. Measure heart rate (BPM) and blood oxygen saturation (SpO2%) hands-free via voice query "Alexa, what's my heart rate?" Features real-time PPG waveform display on TFT, automated health alerts (bradycardia, tachycardia, hypoxemia), historical trend graphs, and Telegram notifications for abnormal readings. Perfect for home health monitoring, elderly care, fitness tracking, and telemedicine applications.
