NOTE: The thermistor resistance can be calculated using following expresion:
[ ] R(T ) = R(25^o C) 1 + TC₁(T − 25^oC) + TC₂ (T − 25^oC)²
Thermopile output voltage is:
Vir = Alpha .[ (T_o4) – (T_a4) ]
where To is the measured object temperature, both To and Ta are in Kelvins
Note: When measuring resistances with an ohm meter, please take care that the internal protection
diodes, as indicated in the functional diagram below, are always reverse biased.
