Virtual Wheatstone bridge based on LabVIEW software for remote laboratory works

Abstract

Nowadays, Virtual Instruments are becoming an important part of solving engineering problems in particular in the area of Automatic Control of Industrial Processes and Education. Due to the continuously increasing performance and flexibility of PC combined with their cost reduction, virtual instruments are successfully concurring the traditional instruments. During the pandemic, covid-19 as a result of adapting the emergent solution in education students and teachers should work from home. Except for lessons and seminars, doing laboratory work faced difficulties to be performed because students should be in the laboratory, which was not possible. In this work we have built a virtual instrument for electrical resistance measurement which imitates in detail the Wheatstone Bridge in our Electrical Measurement Laboratory and tested remotely to measure resistance by interacting with a virtual instrument like with the real instrument.
