What it does

The MAX30102 Pulse Oximeter Heart Rate Sensor Module is an integrated pulse oximetry and heart-rate monitor. It uses photoplethysmography (PPG) with red and IR LEDs to detect blood volume changes for accurate health monitoring.

Key features

  • Pulse oximetry (SpO2) measurement capability
  • Heart rate monitoring with 16-bit ADC resolution
  • Integrated red and IR LEDs with photodetectors
  • I2C interface for easy microcontroller connection
  • Ultra-low power operation for wearable devices
  • High SNR for accurate readings in varying conditions
  • Motion artifact rejection for active monitoring

Good to know

  • Requires firm contact with skin – use finger clip or wrist band
  • Ambient light affects readings – shield sensor from external light
  • Motion artifacts reduce accuracy – keep finger still during measurement
  • Use SparkFun or Maxim library for Arduino
  • Not a medical-grade device – for hobby/educational monitoring only
