HEART

SKU:U029

Description

HEART is built using the MAX30100 chipset.

MAX30100 is a complete pulse oximetry and heart-rate sensor system solution designed for the demanding requirements of wearable devices.

The MAX30100 provides very small total solution size without sacrificing optical or electrical performance. Minimal external hardware components are needed for integration into a wearable device.

  • How do we use this Unit to test the heart rate ?

Put your finger on the detection area.

  • What is the communication protocol between M5 core and this unit?

I2C(0x57).

FAQ

  • QUESTION：The accuracy of the Heart rate unit, what is the resolution?

  • ANSWER：Since it has not been calibrated and officially verified, the data can only be used as a reference, but if the number is suddenly low, you should pay special attention to whether the body is abnormal. The actual test can hold your breath for a period of time and then measure the blood oxygen concentration will be low; The right hand finger measurement is also slightly lower, which may be related to the distance from the heart.
