“…The geomagnetic field is a relatively uniform magnetic field within a few kilometers, and the direction of magnetization of these poles can cause the perturbation of the geomagnetic field, as shown in figure 5 [6][7][8][9]. In the absence of the vehicle, the magneto-resistive sensor signals remained stable, the value as a reference value, a vehicle subjected to interference in the magnetic field, the signal collection value will deviate from the baseline value, the sensitivity of magneto-resistive sensor can distinguish the change of the earth's magnetic field of a thousand, and when a fraction of the vehicle by the effect of the geomagnetic geomagnetic intensity will reach, so when the vehicle near the detection node and its reluctance from both sides or above at a time, the detecting node can be through threshold comparison to determine whether there is a car or after.…”

“…A resistividade aumenta de forma diretamente proporcional com a intensidade do campo magnético. Os magnetorresistores anisotrópicos (AMR) são sensores constituídos de um filme fino de níquel-ferro (permalloy) depositado sobre um substrato de silício, sendo padronizado como uma faixa resistiva (Lenz et al, 1990). Seu princípio de funcionamento é baseado na resistência elétrica do filme, que pode ser modulada pela aplicação de um campo magnético na direção de sua magnetização inerente.…”
