Traditional oscilloscopes and function generators are critical tools for electronics engineers, but they are often expensive, bulky, and limited to local access. This project proposes an innovative IoT-based solution that integrates oscilloscope and function generator functionalities into a single, portable device accessible remotely via a web interface. The system will leverage low-cost hardware components and modern web technologies to enable real-time signal visualization, waveform generation, and remote collaboration.
The oscilloscope module will capture analog signals from circuits, digitize them, and display waveforms on a web dashboard. The function generator will produce standard waveforms (e.g., sine, square, triangular) with adjustable parameters. By hosting the interface on a web server, users can access the device from any location using browsers or mobile devices. This approach reduces costs, enhances accessibility, and supports educational and industrial applications where remote monitoring and control are essential.
We have discussed several waveforms (square waves, clocks etc.) in your CS302 course.
1. Real-Time Signal Acquisition (Oscilloscope):
a. Capture analog signals up to 1 MHz frequency with 12-bit resolution.
b. Display real-time waveforms (voltage vs. time) on the web interface with zoom/pan features.
c. Support multiple trigger modes (e.g., edge, pulse) for stable waveform visualization.
2. Waveform Generation (Function Generator):
a. Generate standard waveforms (sine, square, triangle, sawtooth) with adjustable frequency (1 Hz–1 MHz) and amplitude (0–5V).
b. Allow users to upload custom waveforms via the web interface.
3. Web Interface:
a. Responsive dashboard for real-time monitoring and control of both oscilloscope and function generator.
b. Interactive graphs using libraries like Chart.js or Plotly for dynamic data visualization.
c. User-friendly controls for adjusting parameters (e.g., frequency, amplitude, time based).
4. Remote Access & Security:
a. Secure user authentication (login/password) to prevent unauthorized access.
b. Encrypted communication (HTTPS/WebSocket’s) for data transmission.
5. Data Management:
a. Store historical data (waveforms, settings) in a local or cloud database.
b. Export data in CSV, PNG, or PDF formats for analysis and reporting.
6. Alert System:
a. Notify users via email or in-app alerts when signal anomalies (e.g., voltage spikes) are detected.
7. API Integration:
a. Provide RESTful APIs for integrating the device with third-party applications (e.g., MATLAB, LabVIEW).
8. Multi-Device Compatibility:
a. Ensure compatibility with desktop browsers, tablets, and smartphones.
· Hardware:
a. Microcontroller: Raspberry Pi 4 (for processing and web hosting).
b. ADC/DAC Modules: 12-bit ADC (MCP3208) and DAC (MCP4725) for signal conversion.
c. Sensors: Voltage dividers and op-amps for signal conditioning.
· Software:
a. Backend: Python (Flask/Django framework) for server logic.
b. Frontend: HTML/CSS, JavaScript (React.js), Chart.js/Plotly for visualization.
c. Communication: MQTT/WebSocket’s for real-time updates.
d. Database: SQLite/MySQL for data storage.
e. Development Tools: VS Code, Git, Postman (API testing).
