The M5StickC Heart Rate HAT from M5Stack is a sensor that measures blood oxygen and heart rate. The device is based on the MAX30102 pulse oximetry and heart-rate monitor biosensor module. It uses an I2C communication interface and internally integrates infrared light-emitting diodes, photodetectors, optical components and low-noise electronic equipment. The Heart Rate HAT is non-pluggable and measures the blood oxygen and heart rate by placing the fingertip on the test area of the device. It is ideal for smart medical applications, as well as for designing wearable devices.
Instructions: After the program is running, place your finger on the test area with a stable and fixed pressure.
