ADIMAX30102EFD+T
Overview
The MAX30102EFD+T is an integrated pulse oximetry and heart-rate monitor module that combines dual LEDs, photodetectors, and high-performance optical elements with low-noise electronics. It utilizes an 18-bit ADC and an I2C interface to provide digital biometric data while maintaining a very low shutdown current of 0.7 uA. This sensor is specifically designed for mobile and wearable devices where PCB space and power efficiency are critical.
Why Choose This Part
This module integrates all optical components into a tiny 5.6mm x 3.3mm OESIP package, significantly simplifying optical mechanical design. It operates on a low 1.8V main supply and features a high-resolution 18-bit ADC that ensures reliable signal acquisition even with low perfusion levels.
Applications
Key Specifications
Getting Started
Start development by interfacing the I2C bus with a microcontroller like an ESP32 or STM32. Ensure the 1.8V VDD and 3.3V to 5V LED supply rails are properly decoupled as per the datasheet to minimize optical noise. Drivers are widely available in the Arduino and CircuitPython ecosystems for rapid prototyping.
