A real-time ESP32 IMU dashboard using MPU6050, WebSockets, and Chart.js, built as a PlatformIO project. It uses FreeRTOS under the hood to run sensor data acquisition on a dedicated core task.
A real-time graph showing accelerometer and gyroscope data in action.
- FreeRTOS filtered MPU6050 data streaming.
- Low-pass filter for smoothing noisy sensor data.
- Dual-line chart visualization: Accel & Gyro.
- Fast WebSocket communication using
ESPAsyncWebServer. - Responsive Chart.js interface.
- Structured as a PlatformIO project.
- ESP32
- MPU6050
- Micro USB cable
- WiFi network

pio run --target uploadfspio run --target uploadpio device monitorAfter connecting to WiFi, open a browser to:
http://<ESP32_IP>/Check the serial output for your device's IP address.
- ESP32 reads and filters MPU6050 data at ~40Hz.
- Accumulated in batches of 10 and sent via WebSocket.
- Browser receives data as a JSON array and updates two real-time charts.
