MAX30102 Heart Rate and Oximeter Sensor Module High-Sensitivity Pulse Oximetry & Bio-Sensing Breakout for Arduino in Pakistan

Overview

When developing health-monitoring wearables, fitness trackers, or contactless biometric sensing projects using microcontrollers like Arduino or ESP32, capturing accurate physiological data requires specialized optical sensors rather than basic analog components. Standard sensors struggle with ambient light interference and motion artifacts. The MAX30102 Heart Rate and Oximeter Sensor Module provides an integrated, high-sensitivity bio-sensing solution, combining pulse oximetry and heart-rate monitoring into a single, easy-to-interface I2C breakout board.

Key Features

• Dual-Function Optical Sensing: Integrates both red and infrared LEDs alongside a photodetector to measure blood oxygen saturation (SpO2) and heart rate (pulse) simultaneously.

• I2C Digital Interface: Communicates smoothly with microcontrollers using a standard two-wire I2C interface, minimizing required GPIO pins.

• Ultra-Low Power Operation: Engineered for battery-powered wearable devices, featuring programmable low-power standby modes.

• Ambient Light Cancellation: Built-in optical filtering hardware reduces background light interference to ensure stable, reliable physiological readings.

• Compact Breakout Design: Pre-soldered onto a small, lightweight PCB featuring mounting holes and standard pin headers for effortless breadboard prototyping.

Technical Specifications

Common Applications

• Wearable Health Devices: Core sensing module for DIY smart rings, fitness wristbands, and pulse monitoring wearables.

• Biomedical & IoT Prototyping: Ideal for student engineering projects, health-tracking prototypes, and contactless pulse diagnostic rigs.

Note to customers: Ensure your finger or testing site rests stably against the sensor window without excessive pressure to achieve accurate SpO2 readings!
