METHOD OF MEASURING PHYSICAL QUANTITY USING MOBILE ELECTRONIC DEVICE AND EXTERNAL UNIT Russian patent published in 2015 - IPC G01D21/00 

FIELD: radio engineering, communication.

SUBSTANCE: method of measuring a physical quantity provides use of a mobile electronic device and an external unit. The method includes installing an auxiliary program in the mobile electronic device, and when measuring a physical quantity, switching the mobile electronic device to operation on said auxiliary program during a given time interval, after which, for controlling the external unit, a given audio signal of the mobile electronic device is generated, which is received in the external unit; controlling the conformity of the signal with set requirements, and after establishing said conformity using a sensor which is part of the external unit, generating a signal of measurement information on the measured physical quantity; converting the measurement information signal into an output signal of the external unit, generated in the form of an audio signal whose parameters correspond to the measured physical quantity; receiving, in the mobile electronic device, the output signal of the external unit; storing the measurement result of the physical quantity and notifying the user on the measurement result of the physical quantity; according to the invention, the frequency of the given audio signal of the mobile electronic device for controlling the external unit and the frequency of the output signal of the external unit are selected higher than a limit perceptible for the user.

EFFECT: wider range of measurement devices.
