M5stack Pulsesensor Heart Rate Pulse Sensor Module

M5Stack Pulse Sensor Module (MAX30100)

This M5Stack module features the MAX30100, an integrated pulse oximetry and heart rate monitoring sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals.

Designed for wearable devices, fitness assistants, or medical monitoring applications, it connects easily via the I2C interface to M5Stack units such as the Core, Unit Base, or any compatible microcontroller.

Specifications

• Sensor: MAX30100 (pulse oximetry and heart rate)
• Interface: I2C (default addresses 0x57 or 0x58)
• Supply Voltage: 1.8 V to 3.3 V
• Low power consumption with software-controlled shutdown
• Red and infrared LEDs for optical detection
• High-sensitivity photodetector with integrated optical filter
• Compatible with M5Stack ecosystem (Grove, I2C)

Arduino libraries are available to simplify integration. Direct skin contact is required for accurate measurements.
