▎ 摘　　要

In the paper, the process of manufacturing the graphene Hall-effect structure is presented. Moreover, the measurement system utilizing Helmholtz coils as a source of reference magnetic field is described. The basic functional properties of developed sensor, like sensitivity and offset voltage, were investigated. Also the influence of the supply current on sensitivity and offset voltage and time drift of this parameters were studied. Obtained results indicates that developed graphene Hall-effect sensor exhibits good functional properties and can be utilized in industrial measurements of magnetic field.
