  1. 1. LoRa Based Moisture Sensing System

    University essay from Uppsala universitet/Signaler och system

    Author : Rasha Badran; [2023]
    Keywords : LoRa; moisture sensor; capacitive sensor;

    Abstract : Water is an important parameter for crop growth, and the information about the moisture content in soil at different depths is very useful for farmers to determine the best time to water the soil and to irrigate farmland so as to maximize their yield. This thesis project aims to develop a prototype of a multi-depth moisture sensor probe that is part of a large sensing system used in agriculture. READ MORE

  3. 2. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eriksson Janze Oscar; [2023]
    Keywords : DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

    Abstract : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. READ MORE

  4. 3. Supervised Algorithm for Predictive Maintenance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Haida Lu; [2023]
    Keywords : Long short-term memory; Predictive maintenance; Remaining useful life; Embedded Artificial Intelligence; Långt korttidsminne; förebyggande underhåll; återstående livslängd; inbyggd artificiell intelligens;

    Abstract : Predictive maintenance plays a crucial role in preventing unexpected equipment failures and maintaining assets in good operating conditions in various systems. One such scenario where predictive maintenance has been widely used is in battery management systems for electronic vehicles based on lithium batteries, where the risk of failure can be reduced by predicting the remaining useful life of the lithium battery.

  5. 4. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Teodor Renman; Charlie Ringström; [2023]
    Keywords : Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Abstract : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. READ MORE

  6. 5. External Non-Volatile Memory Management for an STM32 Processor

    University essay from KTH/Hälsoinformatik och logistik

    Author : Johannes Falk; [2022]
    Keywords : Synthesizer; wavetable; STM32; wav; flash; SD card; Synt; STM32; wav; flashminne; SD-kort;

    Abstract : This report details the process of developing libraries to handle data management on two types of non-volatile memory interfacing with an STM32 microprocessor. This was done at the request of Suonobouno AB, who are developing digital and analog synthesizers. READ MORE
