Heart Rate Click MAX30102 modules Sensor MAX30102 Heart Rate Oxygen Pulse Sensor For Arduino

MAX30102 Heart Rate Module Features
MAX30102 sensor is used to detect blood oxygen and heart rate. First, infrared radiation is sent and reflected by hitting the finger, and then the amount of oxygen in the blood is determined by measuring the wave amplitude. Heart rate is also obtained by analyzing the time series response of this radiation.
The MAX30102 is an integrated module compatible with the Arduino and STM32. It integrates a red LED with an infrared LED, a photoelectric detector, an optical device, and a low noise electronic circuit for ambient light suppression. Heart rate and blood oxygen data are also transmitted to the Arduino or other microcontrollers via I2C communication.
