The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It detects pulse by measuring changes in reflected light as blood pumps through your tissues, providing a real-time analogue signal that fluctuates with each heartbeat.
Compatible with both 3.3 V and 5 V Arduino boards, it connects directly via a colour-coded cable with standard male headers — no soldering required. Includes accessories for finger strap and ear clip mounting.
