Description KY-039 Finger detection Heart rate sensor
The KY-039 is a compact heart rate sensor. It detects the heartbeat via the finger. The sensor uses an infrared (IR) LED and a phototransistor. The IR LED illuminates the finger. The phototransistor measures the changes in the light. These changes reflect the heart rate.
It works simply. Place a finger between the IR LED and the phototransistor. The sensor then detects changes in blood volume. He translates these changes into a heartbeat signal.
The KY-039 is small, light and easy to use. It is ideal for hobby projects and experiments. The sensor provides accurate measurements. This makes it a reliable tool for heart rate monitoring.
