Design of Low Power Consumption Crops Stem Flow Meter
摘要
Abstract
In order to better undergraduate the evapotranspiration in the growth process of agricultural crops , a combina-tion based on the low-power MSP430F169 microcontroller and high precision AD 7794 data acquisition system design is proposed, and it is instrumented in the crop transpiration measuring instrument.The AD7794 is a 6-channel true differential gain programmable A /D converter with low power consumption , low noise , high resolution , self-calibration , etc.It is widely used in precision control , precision temperature measurement , precision pressure measurement fields . The data communication between the AD 7794 and the MSP430F169 is SPI bus.关键词
