Portable temperature measuring equipment based on mobile phone distance sensor

Abstract

The invention belongs to the technical field of temperature measurement equipment, and particularly relates to portable temperature measurement equipment based on a mobile phone distance sensor, whichcomprises an infrared lens, a passive pyroelectric sensor, a signal amplification circuit, an AD sampling circuit and a signal processing unit, the output end of the infrared lens is connected with the input end of the passive pyroelectric sensor through a data line. The output end of the passive pyroelectric sensor is connected with the input end of the signal amplification circuit through a data line. The output end of the signal amplification circuit is connected with the input end of the AD sampling circuit through a data line. The output end of the AD sampling circuit is connected with the input end of the signal processing unit through a data line. An optical lens and a passive infrared pyroelectric sensor which are matched with the mobile phone infrared distance sensing equipment are shared, and signal amplification and temperature information processing software is added, so that the temperature measurement function of the intelligent mobile phone is realized, the appearance design of the mobile phone is not influenced, and the influence on the volume, weight and power consumption of the existing mobile phone is reduced to the maximum extent.

Description

Technical field [0001] The invention relates to the technical field of temperature measuring equipment, in particular to a portable temperature measuring equipment based on a mobile phone distance sensor. Background technique [0002] Temperature measurement is a quantitative measurement of the temperature of an object with a temperature measuring instrument. The measurement of the physical quantity of temperature is actually a certain quantity of the object. The physical quantity should change monotonously and significantly with the change of the temperature of the object within a certain temperature range. According to the laws of physics, the temperature of the measured object is displayed by the value of the physical quantity. At present, there are dozens of methods for temperature measurement. According to the physical laws on which the temperature measurement is based and the physical quantity selected as the temperature indicator. [0003] Smart phone refers to a personal...
