Mätutrustning för Solcellers Responstid : En Undersökning i Analog ElektronikSamuelsson, Vilgot, Algeroth von Thiele, Axel January 2023 (has links)
Perovskite solar cells (PSCs) have shown great potential for the future of solar powered energy production. They are however not completely flawless, and one of their more disadvantageous properties are their relatively slow response time. The Department of Materials Science and Engineering at Uppsala University have an interest in the ability to quickly measure the response time of PSCs for further development of optoelectronics. The purpose of this project was to provide an instrument with the ability to easily perform these measurements. The instrument was to be controlled by code from a computer which via usb connected to a microcontroller connected to the rest of the circuit. The electrical circuit was first constructed on breadboards for testing and optimisations, to later construct a circuit board which would neatly fit the entire circuit in a small space. The microcontroller was an Arduino NANO which sampled the current through the PSC at a rate of 33 kHz, which was slower than initially intended. It was however decided that the sample rate was sufficient for the application.

Datový koncentrátor / Data concentratorDvorský, Petr January 2021 (has links)
The topic of this thesis is the design and realization of a modular Data concentrator for various types of measurements in diverse conditions. The device conception, basic principles, design and functionality are described herein. Also, the lightweight protocol design for radio communication, standardized XML format for data storage and cloud usage are described. The electrical design of the device as well as the design of the printed circuit board was made using the Eagle Autodesk electronic design automation software (Eagle Autodesk EDA). The control software written in C/C++ for a target microcontroller (ESP32-WROOM-32) is based on a FreeRTOS platform and ESP-IDF framework. An IDE for managing this software is Visual Studio Code with PlatformIO extension. Selected and used Cloud Platform is ThingSpeak from Mathworks, which uses certain components from Matlab platform.
