Description

The MAX30100 Black Heart Rate Sensor is a highly integrated and compact module designed for measuring heart rate and oxygen saturation (SpO2). Based on the MAX30100 IC from Maxim Integrated, this sensor provides accurate and reliable readings for a wide range of health-related applications, including wearables, fitness trackers, medical monitoring devices, and other health-tracking systems. The sensor uses optical photoplethysmography (PPG) to detect changes in blood volume and provides real-time heart rate and SpO2 measurements. Its small form factor and low power consumption make it perfect for portable and battery-powered devices.

Key Features:

Heart Rate Measurement: Uses optical sensors to detect changes in blood volume, providing heart rate readings.
SpO2 Measurement: Also measures oxygen saturation in the blood (SpO2), a critical parameter for health monitoring.
Integrated LED Lights: Features red and IR (infrared) LEDs, which are essential for taking accurate measurements of heart rate and blood oxygen levels.
Low Power Consumption: Designed for low energy consumption, making it suitable for battery-powered devices.
Small Form Factor: The compact design allows it to be used in wearable devices and small electronics applications.
I2C Interface: Uses an I2C interface, making it easy to integrate with various microcontrollers like Arduino, Raspberry Pi, and others.
Adjustable Sensitivity: The module allows you to adjust the sensitivity for different skin tones and ambient lighting conditions.
Easy to Use: Ready-to-use module with a breakout board, making it simple for developers to integrate into projects.

Specifications:

Heart Rate Measurement Range: Typically 30 BPM to 240 BPM (beats per minute).
SpO2 Measurement Range: Typically 0% to 100% oxygen saturation.
Power Supply: Typically 1.8V to 3.3V (depending on the specific model and application).
Interface: I2C communication protocol.
LEDs: Integrated red LED (660 nm) and IR LED (940 nm) for optical measurement.
Operating Temperature Range: Typically -40°C to +85°C.
Module Size: Compact size of ~20mm x 12mm for easy integration into small devices.
Power Consumption: Low current consumption (typically 0.5mA during measurement).
