|
||
## 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)**.
|
||
|
||
## Product Features
|
||
|
||
- Programmable Sample Rate and LED Current for Power Savings
|
||
- Ultra-Low Shutdown Current (0.7µA, typ)
|
||
- Advanced Functionality Improves Measurement Performance
|
||
- High Sample Rate Capability
|
||
- Fast Data Output Capability
|
||
- GROVE interface
|
||
- Software Develop platform: Arduino
|
||
- Two Lego-compatible holes
|
||
|
||
|
||
