Key Features of PPG Pulse sensor Module
- Plug-and-play analog output - connect directly to any microcontroller ADC pin for instant pulse waveform readings
- Built-in amplification and noise cancellation circuit delivers a clean, reliable signal without external filtering components
- Ultra-compact coin-sized PCB fits seamlessly into wearable devices, finger clips, and custom enclosures
- Wide 3.3V-5V operating range ensures compatibility with Arduino, ESP32, Raspberry Pi, STM32, and virtually any development board
- Low power consumption (~4 mA) makes it ideal for battery-powered wearable and portable health monitoring projects
Perfect For
- Real-Time Heart Rate Monitor: Connect the PPG sensor to an Arduino or ESP32 with an OLED display to build a live BPM (beats per minute) monitor. Use peak detection algorithms to calculate heart rate from the analog pulse waveform and display it in real time.
- Wearable Fitness Tracker: Integrate the sensor into a wrist-worn or finger-clip wearable powered by an ESP32 with BLE. Stream heart rate data to a smartphone app for workout tracking, resting heart rate logging, and daily health monitoring.
- Heart Rate Variability (HRV) Analysis System: Capture inter-beat intervals (IBI) from the PPG waveform and perform HRV analysis using time-domain and frequency-domain methods. Use this data for stress detection, meditation feedback, or autonomic nervous system research.
- IoT Health Monitoring Dashboard: Pair the sensor with an ESP8266 or ESP32 to upload pulse data to ThingSpeak, Blynk, or a custom cloud dashboard. Monitor a patient's or user's heart rate remotely from anywhere in the world via a web browser or mobile app.
- Biofeedback and Meditation Trainer: Build a calming biofeedback device that uses heart rate and HRV data to guide breathing exercises. Display coherence scores on an LCD or trigger LED colour changes and haptic feedback based on relaxation levels.
- Lie Detector / Polygraph Prototype: Combine the PPG pulse sensor with a GSR (Galvanic Skin Response) sensor and a respiration sensor to build an educational polygraph system. Analyse physiological changes in heart rate and skin conductance during questioning.
- Classroom Biomedical Engineering Lab: Use the sensor in academic labs to teach students about photoplethysmography, signal processing, filtering techniques, and biomedical instrumentation. Visualise raw and processed waveforms using Processing, MATLAB, or Python.
- Emergency Alert System for Elderly Care: Design a wearable that continuously monitors heart rate and triggers an SMS
