Duinotech XC3740 Owner's manual

  • I have reviewed the user manual for the Heartbeat Sensor XC3740. This document provides details on the sensor's hardware, including the MAX30102 sensor and connection pins. It also provides information about using Sparkfun MAX3010x library. I'm ready to answer any questions you have regarding its setup, features, or use cases based on the manual.
  • What sensor does the XC3740 heartbeat sensor use?
    Does the sensor come with headers?
    What library is used in the example code?

Hardware
The XC3740 heartbeat sensor uses a MAX30102 sensor to detect small changes in
pulse; It is provided without headers but these can be easily soldered onto the sensor’s
VIN, GND, SDA, and SCL lines. (tip: If you’re not yet great at soldering, we recommend
trying our XC3754 Christmas Tree soldering tutorial first.)

Source code
We use the “Sparkfun MAX3010x” Library by Sparkfun. But other libraries are available.
