Mini Heartbeat Rate Sensor MAX30100 Heart Sensor Module Sensor for Low Power Oxygen Pulse I2C Interface for Arduino - products that work with official Arduino boards

Description:

HEART is build with MAX30100.

MAX30100 is a complete pulse oximetry and heartrate 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 and ? Put your finger on the detection area.

• What is the communication protocol between M5 core and this unit? I2C.

1.EasyLoader is a simple and fast program burner, and each product page has a product-related case program for EasyLoader.

2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click "Burn" to start burning.

3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. Click here to view the driver installation tutorial: https://docs.m5stack.com/#/en/related_documents/establish_serial_connection
