Abstract
- To reduce the interference and improve the weighing precision, a kind of weighing transmitter based on MSP430 Micro-Controller Unit (MCU), which is applicable to resistance strain sensor, is designed for corn yield measurement system and its hardware diagram and software design are given in detail. The design takes full advantage of 24-bit Analog to Digital Converter (ADC) ADS1232 to sample the output of weighing transducer, and weighted average method is used to process data. By comparing the results derived from weighted average method and arithmetic average method, it prove that the former is superior to the latter.
