摘要： A portable electronic device for measuring a physical quantity has at least one sensor device that measures and converts the value or variation of a physical quantity into an analog electrical signal and an electronic device, which acquires the analog electrical signal, converts it into digital format and calculates the engineering value in real time. The device includes two distinct physical units: the first physical unit is a smart mobile electronic device, having an electrical input connecting port for a microphone jack connector, a sound card provided to receive input signals from the connecting port and send them to a processing unit, connected to the card for processing and subsequent emission and/or storage as an output by way of corresponding emission and/or storage; the second physical unit includes the at least one electrical/electronic sensor device, a jack connector corresponding to the microphone connecting port on the first unit, and an electrical/electronic component that converts the analog electrical signal into a frequency value and transmits it to the output jack connector; and wherein the first physical unit includes hardware and software that: receive the analog electrical signal, generated by the at least one sensor device, in the connecting port and convert it into a series of discrete values, the number of which in one second corresponds to the sampling frequency of the smart mobile electronic device; acquire and read the discrete sampled values, in binary data format; store the data in a buffer memory; read the buffer memory and decode the binary data into numerical data; calculate the value of the frequency of the sampled signal by way of a dedicated algorithm; convert, using dedicated software means, the calculated frequency value into a corresponding engineering value for the physical quantity measured, in real time, such that the engineering value for the physical quantity measured is emitted as an output by means of the smart mobile electronic device.
