摘要
介绍了一种以单片微型计算机为核心的普及型农田野外土壤温度和湿度监测系统,着重说明和讨论了土壤温湿度传感器的外部特性、单片机监测仪的软硬件及传感器和监测仪之间的信号传输等问题。研究表明:该系统能够实现一定距离的农田土壤温度和湿度监测。在一般土壤上,盐分和容重的影响可以忽略。
This paper introduces a soil temperature-moisture monitoring system based on single chip computer, which is cheap and adapt to on-farm measurement. Detailed discriptions and discussions are emphasized on the external properties of temperature-moisture sensor, hardware and saftware of the instrument and the signal transmission between sensors and instrument. Experiments show that this system can monitor soil temperature-moisture in a point from a certain distance in farmland.The errors caused by the salt contents and the bulk unit weights in common soils are negligible.
