Key Features of Heart Rate Pulse Sensor Module
- Plug-and-Play Operation: Only three wires - Signal, VCC, and GND - connect directly to any microcontroller's analog input with zero external components required.
- Optical PPG Sensing: A bright green LED illuminates capillary blood flow while a matched photodetector picks up volumetric changes with each heartbeat, delivering a clean analog waveform.
- Wide Voltage Compatibility: Operates reliably at both 3.3V and 5V logic levels, making it compatible with Arduino, ESP32, STM32, and Raspberry Pi (via external ADC) without level-shifting.
- Low Power Draw: Consumes only ~4 mA, ideal for battery-powered wearables, portable health monitors, and IoT nodes.
- Open-Source Library Support: Works seamlessly with the popular PulseSensor Playground Arduino library, providing ready-made BPM calculation, beat detection, and serial visualization.
- Compact & Lightweight: The 16 mm round PCB and flexible 60 cm cable allow comfortable placement on a fingertip, earlobe, or wrist band without restricting movement.
- Real-Time Analog Output: Delivers a continuous waveform that can be sampled at 500 Hz or higher for advanced heart-rate variability (HRV) analysis and R-peak detection.
- Noise-Filtered Design: On-board amplification and filtering circuitry reduces ambient light interference and motion artifacts for stable readings.
- Extensive community and documentation - thousands of tutorials, example sketches, and open-source libraries available online.
Perfect For
- Fitness & Health Wearable: Build a wrist-worn heart-rate monitor that logs BPM to an SD card or streams data to a smartphone via Bluetooth (HC-05/BLE).
- IoT Patient Monitoring System: Pair with an ESP32 and cloud platform (Blynk, ThingSpeak, Firebase) to remotely track a patient's pulse in real time with alerts for abnormal readings.
- Stress & Emotion Detection: Analyze heart-rate variability (HRV) data to estimate stress levels, then trigger calming LED patterns, music, or haptic feedback.
- Biometric Access Control: Combine pulse detection with a fingerprint module to create a liveness-verified biometric lock that rejects spoofed fingerprints.
- Interactive Art & Gaming: Drive LED strips, servo motors, or sound effects that respond to your heartbeat - create immersive installations or biofeedback games.
- Sports Performance Tracker: Log heart rate alongside accelerometer and GPS data during workouts; visualize training zones on an OLED display or web dashboard.
- Academic & STEM Education:
