Este módulo é reponsável por realizar as medições de tensão ou corrente e enviar pela rede CAN


Medições
Tensões em modo diferencial (banco de baterias).
Corrente de entrada (carga das baterias).
Corrente consumida.
Linearizações
Ensaio de funcionamento com cada sensor.
Utilização de métodos matemáticos para determinar a equação que rege o comportamento do sensor, fornecendo uma leitura com melhor precisão.
Envio das informações

Este é um sensor de efeito hall que apresenta em sua saída uma corrente proporcional à corrente que circula por sua janela. É necessário a utilização de um resistor para apresentar um valor de tensão, possibilitando assim a leitura pelo ADC de um microcontrolador. O sinal fornecido pelo sensor passa por uma etapa de filtragem, eliminando possíveis interferências.
Limites elétricos:
Corrente nominal RMS: máx AC 150 [A]
Valor de Pico a Pico: máx 212 [A]
Valores Aplicáveis Para Resistores de Medidas (componente "Rm"):
12V de alimentação e 85°C ambiente. Para ±150A(máx): 0Ω - 40Ω Para ±212A(máx): 0Ω - 3Ω
15V de alimentação e 85°C ambiente. Para ±150A(máx): 0Ω - 78Ω Para ±212A(máx): 0Ω - 30Ω
