Why do we need to be told that a thermal sensor is a FLIR device? It’s a gadget which measures incoming infrared radiation, and provides temperature readings. That FL stands for ‘forward looking’ and it’s the source of the why?
If it were sideways looking, upward or downward looking or even backward looking, the gadget would be no good for reporting the temperature directly in front of the user. So why specify ‘forward looking’ when it's an obvious given?
