Tiivistelmä
The purpose of this project was to design and implement a portable device capable of measuring the power level of specific radio transmissions, and identifying if the signal comes from the desired source. The results are displayed to the user via an Android application and embedded LEDs on the device.
To achieve the desired results, a detector diode circuit and a microcontroller were embedded into a printed circuit board, along with other components responsible for increasing signal-to-noise ratio. Principles of Radio Engineering Design had to be studied for the correct construction of the board. The firmware, written in C language, performed all the component’s control and data analysis.
Field tests with the final product showed that all features worked reliably, displaying correct input power level and signal source detection.
