Heart Rate Pulse Sensor Module Previous 
KY-039 Finger Detection Heartbeat Sensor Module is a simple analog sensor module for measuring heartbeat through a finger. It uses an infrared LED and a phototransistor to detect changes in light transmission through the finger. The module includes an R1 resistor for sensitivity adjustment. It is intended for heartbeat detection, pulse measurement through a finger, DIY projects, and Arduino project development. For stable readings, the module should be isolated from external stray light.
