IR Temperature sensor sense electromagnetic waves in the 700 nm to 14,000 nm range. While the infrared spectrum extends up to 1,000,000 nm, IR temperature sensors do not measure above 14,000 nm. These sensors work by focusing the infrared energy emitted by an object onto one or more photodetectors.These photodetectors convert that energy into an electrical signal, which is proportional to the infrared energy emitted by the object. Because the emitted infrared energy of any object is proportional to its temperature, the electrical signal provides an accurate reading of the temperature of the object that it is pointed at. The infrared signals are passed into the sensor through a window made out of specialty plastic. While plastic normally does not allow infrared frequencies to pass through it, the sensors use a form that is transparent to particular frequencies. This plastic filters out unwanted frequencies and protects the electronics inside the sensor from dust, dirt, and other foreign objects.
