This is a Pulse Oximeter and Heart rate Sensor module based upon Maxim's MAX30100 integrated IC which is an compact low cost integrated solution for measuring Heart Rate as well as Pulse oximeter.
The MAX30102 is an integrated pulse oximeter and heart rate monitor bio sensor module. It integrates a red LED and an infrared LED, photo detector, optical components, and low-noise electronic circuitry with ambient light suppression.
MicroSD Card module is a Micro SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the MicroSD card read and write files. Arduino users can directly use the Arduino IDE comes with an SD card to complete the library card initialization and read-write.
This Mini MP3 Player Module MP3-TF-16P is the perfect integration of hard decoding of MP3 and WMV. The module also customized products, designed for USB card reader, USB sound card, fixed voice, playing low cost development solution.
It is very accurate, as it contains 16-bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time. The sensor uses the I2C-bus to interface with the Arduino.
