Design Support


This application report describes how to implement a single-chip pocket weight scale using a resistive fullbridge sensor and a fully integrated MCU solution using low-power design practices. The included software obtains the measurement results using the MSP430 on-chip sigma-delta analog-to-digital converter (ADC) and displays them on an LCD. A 3-V battery powers the portable device. The design includes a two-point calibration mechanism for offset and gain calibration.
