主要介绍电容式谷物水分检测系统,为了能够实现谷物含水量的现场检测并能把其广泛应用,本系统采用结构简单,成本低,准确度高的电容式传感器进行数字采集。它是利用水分含量影响电容量的原理通过电容传感器检测水分含量。系统软件采用模块式散转结构设计,主程序根据键盘指令实现散转,调用各功能程序模块。 Capacitive grain moisture detection system is mainly introduced in order to be able to achieve on-site testing of grain moisture content and can be widely used, the system uses a simple structure, low cost, high accuracy capacitive sensors for digital acquisition. It is the use of moisture content of the principle of capacitance through the capacitive sensor to detect moisture content. The systematic software adopts the module to disperse the structure design, the main program realizes the scattered turn according to the keyboard instruction, calls each function program module.
