Keyes Finger Heartbeat Measurements
—A Keyes finger heartbeat sensor that detects a pulse optically — light shone through a fingertip changes with each heartbeat, producing a signal a microcontroller can count.
Specifications
- Optical (photoplethysmography) pulse detection
- Fingertip clip or pad sensing
- Analogue pulse waveform output
- Supply 3.3–5 V DC
What you can build with the Keyes Finger Heartbeat Measurements
- Heart-rate display projects
- Biofeedback and wearable experiments
- Science and biology classroom demonstrations
- Interactive art that reacts to a pulse
Compatibility
Arduino analogue inputs; Raspberry Pi and ESP32 via an ADC. For hobby and educational use, not medical diagnosis.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
