Fingerprint, Pulse and Heart-Rate Sensors

Biometric sensors capture physiological data from the human body, enabling projects that monitor health indicators, verify identity, or respond to biological input. They bring healthcare and security applications within reach of Arduino and ESP32 projects.

The range includes optical fingerprint sensor modules with built-in library support, MAX30102 pulse oximeter and heart-rate sensors for SpO2 and heart-rate monitoring, and GSR (galvanic skin response) sensors for stress detection applications.

Biometric sensors are used in DIY access control systems, health monitoring wearables, heart-rate display projects, attendance and identification systems, STEM science projects exploring human physiology, and any maker build where capturing a biological signal is part of the project brief.
