1. 1. Electrical Impedance Profiling of Plants, Coffee and TREO

   University essay from Uppsala universitet/Signaler och system

   Author : Adam Bushara; Sebastian Daniel Clyne; [2022]
   Keywords : ;

   Abstract :  The aim of the project was to investigate the possibility of using low-cost hardware to monitor plant health, measure the impedance of water containing dissolved substances at different concentrations, and observe how the plant impedance is affected compared to auxiliary measurements of soil moisture, ambient light, humidity, and temperature.To measure impedance, we used electrical impedance spectroscopy which gives the impedanceacross a spectrum of frequencies.

   Abstract : Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation.
