Keyestudio MAX30102 Heart Rate Sensor Oxygen Pulse Breakout for Arduino

The Keyestudio MAX30102 Heart Rate Sensor Oxygen Pulse Breakout is a compact, integrated biometrics module designed for Arduino-based projects. Perfect for students, makers, and hobbyists building wearable health tech, this breakout simplifies the process of measuring pulse and blood oxygen levels.

Integrated biometric sensing

Built around the MAX30102EFD component, this module combines a pulse oximeter and a heart rate monitor into a single compact unit. It integrates an infrared LED, a photodetector, optical elements, and low-noise electronic circuitry with ambient light suppression.

Simple I2C communication

The breakout features an I2C communication interface to transmit collected data directly to your microcontroller. Once received, the MCU can easily calculate the real-time heart rate and blood oxygen levels.

Easy mounting and installation

To help you securely integrate the sensor into your custom wearables, enclosures, or prototyping rigs, the board includes a pre-drilled 3mm diameter fixing hole.

Electrical specifications

Operating at a working voltage of DC 5V, the sensor draws a working current of 60mA with a maximum power consumption of 0.3W. This low power draw makes it highly suitable for portable, battery-powered maker projects.

Compact form factor

Measuring just 20mm by 36mm by 7mm and weighing only 2.5g, this lightweight board fits easily into tight spaces. It connects via a 4-pin interface with a standard 2.54mm pitch.

Industrial ratings and resources

Designed to operate in temperatures ranging from -25 degrees Celsius to +65 degrees Celsius, this ROHS-compliant module is built for durability. Developers can quickly get started using the available Arduino software and wiki tutorials.
