Free & Open‑Source Pulse‑to‑VRChat Utility!

What It Is

A free, open‑source desktop application (built in C#) that streams your heart‑rate data from a Bluetooth Low‑Energy (BLE) pulse‑oximeter directly into VRChat via OSC—no phone or web apps required

Features

  • Native desktop Bluetooth support — connect your pulse‑oximeter (e.g. CooSpo H808S) straight to your PC and stream real‑time BPM
  • Alternative phone‑assisted mode — if your PC lacks BLE, use a companion Android app as an intermediary (same app bundle, still no web).
  • Seamless VRChat integration — sends heart‑rate data via OSC to VRChat on port 9000, compatible with popular avatar setups like HRtoVRChat_OSC and vrc‑osc‑miband‑hrm; includes extra parameters like session peaks
  • Completely open‑source under the MIT license—review, customize, and build freely.

Requirements

  • Hardware: BLE pulse‑oximeter (tested with CooSpo H808S)
  • PC Bluetooth (built‑in or adapter), or Wi‑Fi connection + phone (Android 13 or newer)
  • PC OS: Windows 10/11 (for BLE/WPF support)
  • VRChat: OSC functionality enabled (port 9000 by default)

How It Works

  1. Connect your device via BLE on PC, or use the Android app paired with phone & PC on the same network.
  2. Launch HeartRateMonitorVRC and select your pulse‑oximeter.
  3. Done!

Why Use It

  • Immersive VR: Let your avatar physically reflect your pulse for cosplay, roleplay, or fitness environments.
