Abstract: The paper is aimed at the problematic of vehicle detection, which is based on the employment of standard digital anisotropic magneto-resistive magnetometer sensors. There is a number of suitable sensor modules available in the market, which can be used for this purpose. The sensors, however, differ in parameters, such power consumption, maximal sampling frequency, measurement range, or measurement sensitivity. The aim of this paper is to provide a kind of coherent comparison of such as sensor performance. The bank of sensors is tested first in the laboratory environment and then, the sensors with the best results are further tested in the outside scenario. During the test, the needs of the final application were stressed, that the proper sensor module will be chosen. This paper is an extended version of the conference paper 1, with an added section dedicated to the outside measurements.

Keywords: Magnetometer, Sampling, Performance, Power Consumption, Vehicle Detection.
