Before we ship any hardware, we record full operational bench tests demonstrating how your custom device responds to physical inputs, sensor triggers, and wireless commands.
Photoplethysmograph: Human Pulse Rate Monitor
In this video, we build a real-time heart rate and pulse rate monitor (Photoplethysmograph) from scratch using an Arduino Uno R3, a PulseSensor optical sensor, and an I2C LiquidCrystal display. Watch how custom C++ signal calibration code filters noise to display live pulse readings on screen! This can be customized in various ways.
