void Temperature::CalcTemp

(

float

sensor

)

Convert the analog value to the respective value.

As the call to the temperature reading is not a high priority task and does not need very high responsivity, when the analog data are read they are immediately converted to the three temperature scales: Celsius, Kelvin and Farehneit.
