Abstract
A multi-dimension detector with half bridge load cells, which includes an analog to digital converter (ADC), a plurality of half bridge load cells, an analog multiplexer and a central processing unit (CPU). The CPU controls the analog multiplexer to form a plurality of full bridge load cells by selecting either two of the half bridge load cells and detect a plurality of measures corresponding to an object. The ADC converts analog signals corresponding to the plurality of measures into digital signals. The CPU determines all dimension values of the object according to the plurality of measures corresponding to the digital signals.
