MAX30100 Heart Rate Pulse Blood Oxygen Sensor Module

The MAX30100 Heart Rate Pulse Blood Oxygen Sensor Module is a sensor designed for non-invasive measurement of heart rate and blood oxygen saturation (SpO2). It combines two LED drivers, a photodetector, optimized optics, and a low-noise analog signal processing system in a compact and low-power module, making it suitable for wearable devices, fitness trackers, and health monitoring applications. This sensor is widely used in health monitoring systems to track vital signs in real-time.

Specifications

1. Operating Voltage: 1.8V to 3.3V (commonly powered by 3.3V in most applications).
2. Operating Current: Low power consumption, typically in the range of 0.7mA (during active measurement) to 1.1mA (LED current), with standby current as low as 0.7μA.
3. Communication Interface: I2C (requires two wires: SDA for data and SCL for clock).
4. Heart Rate Measurement Range: Capable of detecting heart rates typically ranging from 30 to 240 beats per minute (BPM).
5. SpO2 Measurement Range: Measures blood oxygen levels in the range of 0% to 100% (usually accurate for 70% to 100% in practical scenarios).
6. Sampling Rate: Programmable, typically up to 100 samples per second.
7. LED Wavelengths: Red LED at 660 nm and IR LED at 880 nm.
8. Dimensions: Typically around 12.7mm x 11.4mm.
9. Temperature Measurement Range: -40°C to +85°C.
