KY-039 Heartbeat Module
Overview:
The KY-039 Heartbeat Sensor Module is a small and cost-effective sensor used to detect heartbeats by using an infrared (IR) LED and a phototransistor. When a finger is placed between the IR LED and the phototransistor, the sensor detects changes in blood flow caused by the heartbeat, allowing it to provide an analog output signal. This sensor is typically used in healthcare monitoring, fitness trackers, and biofeedback systems. It’s compatible with Arduino, Raspberry Pi, and other microcontroller platforms.
