Nathanne,
I'm trying to understand converting the TO pin voltage to a human readable celsius or fahrenheit. I see in your example you are calling ph4502c.read_temp(). However, when I look at that function, it seems like it just returns the straight pin value, not any sort of conversion.
int PH4502C_Sensor::read_temp() {
return analogRead(this->_temp_pin);
}
For example, I'll just get a value of 752.00. I can't find any datasheet explaining what the equation should be for temperature.
Thank you.
