PulseSensor Kit with TPU Stabilizer Ring

Designed by the original PulseSensor creators, this open-source analog pulse-sensing kit helps students, artists, and developers add live pulse-wave signals to classroom activities, interactive art, biofeedback experiments, and maker projects.

The TPU Stabilizer Ring is included. It helps maintain steadier sensor contact. Signal quality still varies with placement, finger pressure, movement, ambient light, the development board’s analog-to-digital converter, and software settings.

Start Here: identify the parts, prepare the sensor, connect it, and see your first waveform.

What’s in the box

• One PulseSensor with attached 24 in (610 mm) color-coded cable and male headers
• One TPU Stabilizer Ring
• One Velcro finger strap
• One ear clip
• Transparent vinyl insulation dots

A development board, computer, and other project hardware are not included.

Connection and compatibility

PulseSensor produces an analog output and requires a compatible development board with an analog input (ADC). Board-specific voltage, ADC, pin, and software setup may be required. Use a validated example for your board before connecting.

• Purple: analog signal
• Red: power; follow the board-specific voltage guidance
• Black: ground

Examples and tutorials are available for selected Arduino, ESP32, Raspberry Pi Pico, and micro:bit boards. A board having an analog input does not by itself mean every software example has been tested on that board.

Prepare before use

Do not place exposed electronics against skin. Apply an included transparent vinyl dot to the sensor face and fully insulate the rear electronics using the preparation materials and method supplied for your current kit. Then use the ring, strap, or ear clip with light, steady contact. If your kit or preparation method is unclear, contact support before use.
