KY-039 Heartbeat Sensor

Description

The KY-039 Heartbeat Sensor Module is a small, efficient device used to monitor heart rate through infrared light detection. By placing a finger between the IR LED and photosensitive diode, blood vessel dilation with each heartbeat alters the infrared light reflection, producing a pulsating signal. This signal is shown as an analog output, making it ideal for heart rate monitoring applications. Its simplicity and compatibility with microcontrollers make it an excellent choice for health-focused projects.
