The 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.
What is in this drawing
Read the decisions behind it.
01
Use a diode peak detector to convert the LNB IF signal into a DC voltage readable by the Arduino ADC
02
Use an I2C LCD to minimize wiring and free up Arduino pins
03
Add a pushbutton for field calibration of the signal threshold
Reusable for DIY satellite finders, RF signal strength meters, and Arduino-based test equipment requiring visual feedback.
