All about the product
The KY-039 is a compact module designed to measure pulse frequency using infrared reflection. The sensor uses an IR diode and a phototransistor to analyze blood flow changes in the user's finger. With an analog signal output and compatibility with Arduino, Raspberry Pi, and ESP32 platforms, the module is ideal for educational projects, biometric systems, portable devices, and DIY projects related to body parameter monitoring.
