MAX30100 Pulse Oximeter Heart Rate Sensor Module

MAX30100 is an integrated pulse oximeter and heart-rate monitor sensor solution

The MAX30100 is an integrated sensor solution designed for pulse oximetry and heart rate monitoring. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals.

• Integrated LEDs: Infrared (IR) and red LEDs.
• Photodetector: Measures absorbance of pulsing blood.
• Optimized Optics: For accurate readings.
• Low-noise Analog Signal Processing: Ensures signal clarity.
• I2C Interface: Easy integration with microcontrollers.
• Interrupt Pin: For efficient signal processing.
• Power Supplies: Operates from 1.8V and 3.3V.
• Low Standby Current: Can be powered down through software, allowing the power supply to remain connected at all times.
