Unit Heart
Description
Unit Heart is a blood oxygen and heart rate sensor. It integrates MAX30100, providing a complete pulse oximeter and heart rate sensor system solution. This is a non-invasive blood oxygen and heart rate sensor, integrating two infrared LEDs and a photodetector. Its detection principle is to illuminate with infrared LEDs and detect the ratio of oxygenated to deoxygenated red blood cells to determine blood oxygen levels.
Testing method: After the program runs, place your finger on the detection area.
Heart Unit communicates with M5Core via the I2C protocol, I2C address: 0x57
