Abstract

The invention discloses a hand-held electronic equipment-based galvanometer. The galvanometer comprises a three-axis electronic compass, a processing chip and a display screen, wherein an X axis, a Y axis and a Z axis which are mutually vertical are defined on the three-axis electronic compass; the processing chip is electrically connected with the three-axis electronic compass; the processing chip controls the display screen to display a carrier lead which is placed at a preset position of a display interface of the display screen; the three-axis electronic compass measures the magnetic induction density value of the carrier lead along the negative axis direction of any one of the X axis, the Y axis and the Z axis; and the processing chip acquires the magnetic induction density value from the three-axis electronic compass and acquires the current value passing through the carrier lead according to the magnetic induction density value. Therefore, the hand-held electronic equipment has a current measuring function, the requirements of maintainers or electron enthusiasts can be greatly met, and the user experience on the hand-held equipment can be improved at the same time.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of consumer electronics, in particular to an ammeter based on a handheld electronic device. Background technique [0002] At present, various handheld electronic devices such as tablet computers, mobile phones, PDA (personal digital assistant, personal digital assistant) have been widely popularized, and various applications based on handheld devices emerge in an endless stream, but in the existing handheld electronic devices, Often does not provide a current measurement function. [0003] For maintenance personnel or electronics enthusiasts, when encountering unexpected situations and needing to measure the current passing through a certain current-carrying wire, they often only have handheld electronic devices such as tablet computers, mobile phones, and PDAs at hand, and do not carry Dedicated current meter. [0004] Therefore, if an ammeter based on a handheld electronic device ca...
