CASE ANALYSIS
Scenario
A field technician needs a portable Arduino-based satellite signal detector with LCD display to align dish antennas by reading LNB IF signal strength.
Key decisions
- Use a diode peak detector to convert the LNB IF signal into a DC voltage readable by the Arduino ADC
- Use an I2C LCD to minimize wiring and free up Arduino pins
- Add a pushbutton for field calibration of the signal threshold
When to reuse this
Reusable for DIY satellite finders, RF signal strength meters, and Arduino-based test equipment requiring visual feedback.
