The Pulse Rate & Heartbeat Sensor Module detects heart rate using photoplethysmography (PPG) with an infrared LED and photodetector. It measures pulse by detecting blood volume changes in fingertip tissue.
Key features
- Photoplethysmography-based pulse detection
- Infrared LED + photodetector
- Analog output
- Low power consumption
- Compact module
- Easy finger placement
Good to know
- Place fingertip gently on sensor – do not press hard
- Ambient light affects reading – shield sensor
- Use averaging algorithm for stable BPM reading
- Not a medical-grade device
- Motion artifacts affect accuracy
