ADC 12 bits – Sensor de Temperatura
► O modulo ADC contem um sensor de temperatura conectado a uma entrada ADC.► A funcao de transferencia segue a equacao:
Temp = 25 - ((VTEMP -VTEMP25) ÷ m)
onde:VTEMP: tensao no sensor de temperatura na temperatura ambienteVTEMP25: tensao no sensor de temperatura a 25°C (usar valor definido no
datasheet)m: “Cold slope” ou “Hot Slope”. Produto tensao x temperatura em V/°C definido em
dois valores distintos. (Descricao abaixo. Valores definidos no datasheet)
► Para efetuar o calculo:• Ler o canal do sensor de temperatura (VTEMP)• Comparar VTEMP com VTEMP25.
� Se VTEMP > VTEMP25, aplicar m = Cold Slope na equacao� Se VTEMP < VTEMP25 aplicar m = Hot Slope na equacao
• Efetuar o calculo e obter o resultado da temperatura
