In this project we will see how to build a heart rate detection system, we use a pulse sensor and an OLED display, all controlled by an Arduino Nano. The sensor detects the person heartbeat and converts it into electrical signals and pulses. The signals are amplified using a signal conditioning circuit and processed by…
Inspired by a Star Trek Tricorder, the maker has converted a handheld gyroscopic toy into an original handheld Arduino controlled heart rate monitor. The device consists of an Arduino Pro Mini with a pulse sensor and an OLED display stuffed inside the handle, which conveniently already had accommodations for three AA batteries. After opening up the handle, I…
Yesterday we talked about Hackaday Prize 2015, here’s one of the really interesting projects presented: an open source Arduino compatible PPG Oxymeter. Good luck to Rajendra Bhatt! Easy Pulse Plugin is an open-source pulse sensor based on the principle of photoplethysmography (PPG), which is a non-invasive technique of measuring the cardiovascular pulse wave by detecting…
