MAX30102 Oximeter Heart Rate Beat Pulse Sensor Ok, let me cover myself by pointing out that you shouldn't rely on this as medical device, but what fun you can have building your own oximeter and pulse measuring sensor using the MAX30102 I2C Sensor. The MAX30102 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices.The MAX30102 operates on a single 1.8V power supply and a separate 3.3V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times. Jeff Magee has put together some comprehensive documentation and code to build your own: https://create.arduino.cc/projecthub/jeffreymagee/attiny85-pulse-oximeter-and-photoplethysmograph-e3f907 Either on an ATTINY85: or on a Nano: If you need the OLED DISPLAY, CLICK HERE.
