sensor is coming

The sensor from Vereta is finally coming. Surprisingly, they send us two thermocouples type K. One is called as active sensor which measures the perceived temperature and another is the passive sensor only measures operative temperature.

To get the perceived temperature, we must provide another temperature sensor that sense the temperature of ADDA card. Now we are using IC: TMP01

And the equation for perceived temperature will be :
GT = ((Temp_active - Temp_card ) - 13.00) * 1.05) + Temp_card

Equation for the air velocity (m/s) is
v = ((Temp_passive - Temp_active)+ 14.4)*0.06
ps : the output is not linear, = 0.4 at 0.4 m/s
