M5Stack® Mini Heartbeat Rate Sensor MAX30100 Heart Sensor Module Sensor for Arduino Low Power Oxygen Pulse I2C Interface

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. Product Features: Programmable Sample Rate and LED Current for Power Savings Ultra-Low Shutdown Current (0.7A, typ) Advanced Functionality Improves Measurement Performance High Sample Rate Capability Fast Data Output Capability GROVE interface Software Develop platform: Arduino Two Le go-compatible holes Product Size: 32.2mm x 24.2mm x 8.2mm Product weight: 4.6g Package Included: 1x HEART Unit 1x Grove Cable Related Link: Offical Video Forum Datasheet - MAX30100 MAX30100lib EasyLoader click to download EasyLoader 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.
