A Survey of the Effectiveness of a Signal In a Wireless Analog and Digital SystemLundholm, Rickard, Bashir, Zaid, Kurowski, Sven January 2015 (has links)
The aim of this paper is to study the different parts of a wireless system in order to better understand the signal properties and what key factors changes the signal during its transmission. Two transmitters were created, an FM transmitter that transmits analog data and an Arudino board programed to convert data to bits before its transmission. The acquired signals were then compared to the original signal noting how differently the data had changed. To understand the antennas contribution to the system a simulation was done using High Frequency Structural Simulator. A description of the analysis on the different acquired signals was done to determine the best applications they might have.

Gränsnitt för trådlös insamling av solcellsrelaterad data / Interface for wireless collection of solar dataSöderberg, Eric, Caesar, Magnus, Näslund, Oliver, Annerbo Lång, Elias, Eriksson, Jakob January 2024 (has links)
With the increasing demand for renewable energy, solar cells have become a crucial technology in meeting this need. Optimizing the placement of solar cells is essential and can be achieved by tracking their performance data. This project's goal was to develop an interface for collecting primarily solar cell-related data, although it is versatile enough to handle any type of data. The report details the sensors and components used in the standard interface. The final product is not strictly a transmitter or receiver, but includes a piece of breadboard allowing for the implementation of various circuits. Additionally, the practical aspects of data collection using a Raspberry Pi and database services are discussed. The completed system features transmitter and receiver circuits, which can be expanded into a larger mesh network as needed.
