Complex impedance measurement system for environmental sensors characterization
Mitar Simić · 2014
In this paper description of complex impedance measurement system for environmental sensors characterization is described. Device can be used as standalone device but it also can be connected to the PC through serial communication. Color display is used for local graphical presentation of measured values while for online PC analysis specialized application was developed. System verification was done in frequency range from 5 to 100 kHz for impedance range from 100 'Ω to 100 k'Ω. Verification of impedance magnitude and phase angle measurement results as done as proof that developed system can be used for characterization of sensors for air, soil and water pollution monitoring developed within SENSEIVER project.
