Conventional oscilloscopes are bulky, heavy, and not always practical for working with microelectronics or compact setups. Carrying a full-sized oscilloscope for quick signal inspection, basic waveform visualization, or field diagnostics can be inconvenient and inefficient.
InduScope is a compact, IoT-enabled oscilloscope built using the IndusBoard Coin. It leverages the ESP32-S2’s ADC capabilities and a simple external conditioning circuit to capture AC and DC signals. With built-in Wi-Fi, InduScope streams real-time waveforms to a web interface accessible on phones, laptops, or smart TVs, eliminating the need for a traditional display unit.
Key Features
- Ultra-compact, portable oscilloscope design
- IoT connectivity with wireless waveform visualization
- Web-based oscilloscope interface with real-time plotting
- Adjustable time and voltage scales via sliders
- AC/DC coupling support using a switchable capacitor
- Extended input range up to ~33V DC and 220V AC (scaled)
- Input protection using voltage divider and clamping diodes
- Waveform capture and snapshot grid for analysis
Applications
- Quick signal analysis during electronics prototyping
- Educational use for learning waveform behavior and ADC sampling
- Field diagnostics and troubleshooting
- Embedded and IoT development testing
- Portable alternative for basic oscilloscope needs
InduScope transforms the ESP32-S2 into a practical, wireless oscilloscope that prioritizes portability and accessibility. While it doesn’t replace a high-end lab oscilloscope, it offers a powerful, compact solution for everyday signal visualization, making oscilloscopes more approachable for makers, students, and engineers alike.
