摘要
本设计采用典型芯片AT89C51为核心,通过选择相应光源及色彩传感器,并设计和光电检测元器件相适应的信号检测电路,利用ADC0809进行模数转换,将检测结果通过液晶显示(LCD1602)和语音播报(ISD1420)输出,实现了便携式颜色检测仪的设计。本设计具有体积小、成本低、功能强、智能化等特点,且现场运行效果良好。
Typical chip AT89C51 is used as the core. This paper introduce choosing appropriate light source and color sensors, and design and photo detector components suitable signal detection circuit, using ADC0809 to realize analog to digital convertion , output the results by the liquid display （LCD1602） and the Speech broadcast （ISD1420） , and using the press to control the color information. Not only hardware design is simple, but also the software design is clear. The whole system is small and intelligent, low in cost, the function is strong. The running effect is also satisfactory.
