MAX30102 Pulse Oximeter Heart Rate Sensor Module

The MAX30102 is a pulse heart rate sensor module that is based on the photoplethysmogram (PPG) principle. It uses two LEDs (infrared and red) and a photodetector to detect changes in blood flow, and then converts these changes into an electrical signal that can be read by an electronic device.

The module is designed to be small and low-power, making it well-suited for use in portable and wearable devices. It also includes an integrated ambient light rejection feature, which helps to improve the accuracy of the heart rate measurements by reducing the impact of ambient light on the readings.

The module can be easily interfaced with a microcontroller or other electronic device via an I2C interface, and it also includes an integrated interrupt function that can be used to trigger an event when a new heart rate reading is available.

The MAX30102 is a widely used module in the field of healthcare, fitness, and wellness applications. It is also commonly used in DIY projects and prototyping projects, such as heart rate monitoring devices, pulse oximeters, and other devices that require heart rate or blood oxygen saturation measurement.
