技术资料 基于单片机的水产品新鲜程度检测的报警器研制与性能
目的设计一款基于单片机的警报器,实现对水产品新鲜程度进行检测与警报,并对其性能进行评价。方法使用AT89C51单片机为主控制芯片,通过气体传感器MQ-137来检测水产品贮藏中产生的氨气等化合物,通过测得的氨气浓度从而判断水产品是否新鲜,及其新鲜程度。结果报警器会根据设定的阈值进行检测以及发出警报,同时液晶屏显示出对应 ...
测试测量 基于Multisim 10的矩形波信号发生器仿真与实现
在Multisim 10软件环境下，设计一种由运算放大器构成的精确可控矩形波信号发生器，结合系统电路原理图重点阐述了各参数指标的实现与测试方法。通过改变RC电路的电容充、放电路径和时间常数实现了占空比和频率的调节，通过多路开关投入不同数值的电容实现了频段的调节，通过电压取样和同相放大电路实现了输出电压幅值的调节 ...
