The MAX30102 Heart Rate and Pulse Oximeter Module is a high-precision optical sensing board designed for real-time biometric tracking. Featuring Maxim's advanced MAX30102 IC, this module measures oxygen saturation and pulse rate by emitting two distinct light wavelengths (red and infrared) and detecting blood absorbance levels through a low-noise photodetector—a setup ideal for fingertip measurements.

Signals are filtered on-chip and sent directly to your microcontroller via the I2C interface. The module operates at 3.3V and includes a programmable interrupt (INT) pin alongside a 7-pin connection header for seamless wiring with Arduino, ESP32, and STM32 boards. For best performance, maintain consistent finger placement, avoid high motion, and apply gentle pressure during testing. This reliable development board is brought to you by Famephase Electronic Accessories.
