Abstract
PIR thermometer is a kind of infrared thermometer that makles use of the pyroelectricity effect,it uses the blackbody radiation laws as the theories foundation,it is the e that the optical theories and micro—electronics lear prehensive pared to the way of traditional temperature measurement,it has a series of merits,such as short in response time,non-contact,noninterference to temperature field ,long useful time and convenient operation,etc.
This paper introduces the basic principle of PIR and the method of realization in the technique that the IR thermometer's present stage as a put forward and develop a kind of measure system according to the embedded microprocessor of high performance paper introduces posing and the method of that system in gives the hardware principle diagram and design flow chart of the factors that influence PIR thermometer’s accuracy and the related interference of hardware and software are analyzed in detail,and adopted to corresponded following work is done:
The present condition and classification of IR thermometer are introduced elaborately,and the meaning of this research is point out;The principle of PIR is introduced;The way to measure IR radiation is presented;The ARM microprocessor is made detailed introduction,a
