keyestudio XD-58C Pulse Sensor Module

The keyestudio XD-58C Pulse Sensor Module is a plug-and-play heart rate sensor designed for students, athletes, makers, and developers looking to integrate biometric data into their projects. Simply clip it onto a finger or earlobe to start capturing real-time pulse readings. It is an ideal tool for creating interactive games, mobile applications, and health-monitoring prototypes.

Real-time heart rate monitoring

This compact sensor measures heart rates by clipping comfortably onto a finger or earlobe. It is highly versatile, making it perfect for students, artists, athletes, and game developers creating interactive, bio-responsive projects.

Integrated signal conditioning

To ensure clean and reliable readings, the module features an integrated optical amplifier and a noise elimination circuit. This hardware-level filtering helps stabilise the analog signal before it reaches your microcontroller.

Open-source app support

The sensor is supported by an open-source application program that displays your real-time heart rate in a visual graph. This makes it easy to test your setup and visualise pulse data immediately.

Flexible power and analog output

Operating on both 3.3V and 5V power supplies, the module provides an analog output signal ranging from 0V up to your supply voltage. It features a green LED with a peak wavelength of 515nm for optical pulse detection.

Easy Arduino integration

Designed for straightforward connection to Arduino and other microcontrollers, the module is backed by a wiki tutorial page. This helps you get your hardware wired up and programming started quickly.
