摘要
水的浊度是反映水质优劣的一项重要指标。为了检测液体中悬浮物的浊度,采用了AT89C51、硅光电池、ICL7650等器件作为硬件电路,根据散射光的光强Is与浊度T成正比关系,设计了光电浊度测量系统。系统采用硅光电池接收散射光,并转换为电信号,由ICL7650构成的放大器进行放大,由单片微处理器记录和换算,最后送液晶LCD1602显示结果。
The turbidity of water is an important index to reflect the quality of water, in order to detect the turbidity of suspended things in liquid, using AT89C51, silicon photocell, ICL7650 components as hardware circuit, according to the proportional relationship between the scattered light intensity I. and turbidity T, this article designs photoelectric turbidity measurement system. The system adopts the silicon photocell to receive scattered light and converts it to be an electrical signal, which is amplified by the amplifier composed of ICL7650, which is recorded and conversed ＂by a single chip microprocessor and delivered to LCD1602 to display the results.
