This is a breadboard friendly breakout board for the Maxim MAX30105 reflectance, particle, and pulse ox sensor. This library should work with other MAX3010x sensors including the MAX30102, MAX30101, ...

Processing software that works with the Arduino Pulse Sensor Amped module. Displays heart rate variation data in graphical format. Readme This file contains hidden or bidirectional Unicode text that ...

The pulse sensor uses a piezo element pressed against a fingertip to detect changes in pressure resulting from blood flow. It can be picky about placement, but finding sweet spot can yield ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.
