+ * awfully large number. Not -40 degree to 85 degree.
+ * 
+ * Considering how ADCs usually work, this big 16 bit number seems to be a quantization for 
+ * the sensor's full range: -40 to 85, 125 degrees.
+ * 
+ * Also, it says (at Table 4) the value is zero when the temperature is around 25°C.
+ * 
+ * So I've devised this code... but it seems temperature read itself is a bit higher than
+ * real temperature.
