Description

The M5StickC Heart Rate Hat is a compact blood oxygen and heart-rate sensing HAT for M5StickC projects. It integrates the MAX30102 module to provide a pulse oximeter and heart-rate sensor system in a small add-on format.

The MAX30102-based design uses infrared LED illumination and optical detection to help determine blood oxygen levels and heart rate. It integrates infrared LEDs, a photodetector, optical components, and low-noise electronics with ambient light suppression for more stable sensing results.

With I2C communication at address 0x57, fast data output, a programmable sampling rate, and adjustable LED current, the M5StickC Heart Rate Hat is suitable for wearable device prototypes, heart-rate and blood-oxygen collectors, and smart healthcare development projects.

Usage Note

After the program is running, keep your finger stable with constant pressure on the detection area.
