Methods and systems for determining temperature of an object

A system for determining a temperature of a remote object comprising:

• an infrared temperature sensor;
• a temperature sensor configured to detect a temperature of the infrared sensor;
• a memory comprising a lookup table of infrared temperature sensor output voltage versus object temperature and associated information;
• and
• a processor communicatively coupled to said infrared temperature sensor, temperature sensor, and memory wherein the processor is programmed to:
• store in memory, a lookup table relating an output voltage of an infrared sensor to a temperature sensed by the infrared sensor V(TO, TA);
• determine a voltage output of the temperature sensor that corresponds to a temperature TA proximate the infrared temperature sensor;
• determine a first voltage as a function of the temperature TA proximate the infrared sensor and a reference temperature TREF, V(TA,TREF);
• determine a second voltage as a function of the temperature of the object TO and the reference temperature TREF, V(TO,TREF) by combining the determined temperature sensor voltage output and the first voltage;
• and
• determine a temperature of the object TO from the lookup table using the second voltage.

A computer program embodied on a computer readable medium for detecting a temperature TO of a remote object, said program comprising a code segment that:

• stores in memory, a lookup table relating an output voltage of an infrared sensor to a temperature sensed by the infrared sensor V(TO, TA);
• determines a temperature sensor voltage output corresponding to a temperature TA proximate the infrared sensor;
• determines a first voltage as a function of the temperature TA proximate the infrared sensor and a reference temperature TREF, V(TA,TREF);
• determines a second voltage as a function of the temperature of the object TO and the reference temperature TREF, V(TO,TREF) by combining the determined temperature sensor voltage output and the first voltage;
• and
• determines a temperature of the object TO from the lookup table using the second voltage.
