The article presents the prototype of the SmartEIT measuring device construction based on the Raspberry Pi platform using electric impedance tomography. The measurement with the device consists in placing electrodes on the tested object, two electrodes are connected to alternating current, and the voltage drop is measured on the other. SmartEIT enables measurements on 16 electrodes. The electrodes can be made of copper without a shield or covered with conductive rubber, depending on the tested object. In each cycle, SmartEIT forces AC flow with a sinusoidal waveform with a constant amplitude and a frequency of 1 kHz between the two farthest electrodes. The current is relatively low, selected during measurements so that the capacity of the power source is not exceeded.

W artykule przedstawiono prototyp konstrukcji urządzenia pomiarowego SmartEIT oparty na platformie Raspberry Pi z wykorzystaniem elektrycznej tomografii impedancyjnej. Pomiar za pomocą urządzenia polega na umieszczeniu elektrod na badanym obiekcie, dwie elektrody są podłączone do prądu przemiennego, a spadek napięcia jest mierzony na pozostałych. SmartEIT umożliwia wykonywanie pomiarów na 16 elektrodach. Elektrody mogą być wykonane z miedzi bez osłony lub pokryte gumą przewodzącą, w zależności od badanego obiektu. W każdym cyklu SmartEIT wymusza przepływ prądu przemiennego sinusoidalnym przebiegiem o stałej amplitudzie i częstotliwości 1 kHz między dwiema najdalszymi elektrodami. Natężenie prądu jest stosunkowo niskie, wybrane podczas pomiarów, tak aby wydajność źródła prądu nie została przekroczona.
