Abstract

A temperature measurement apparatus allows for accurate temperature measurement in both the sun and the shade using two different thermal sensors. A black sensor has an infrared absorbent surface and a white sensor has an infrared reflecting surface. Using the measurements from these two sensors, a series of equations calculate the correct ambient temperature regardless of where the measurement device is located and ensures accurate readings using a performance check system.
