How the Pulse Sensor Heart Rate Sensor Works

This heart rate sensor uses an APDS-9008 ambient light sensor and a high-brightness green LED to sense your pulse. It detects small changes in reflected light as blood pulses through your fingertip or earlobe and outputs a clean, readable analog pulse signal. Pair it with Arduino, Raspberry Pi, or almost any other microcontroller for instant heart rate monitoring.
