一、前言在频谱和颜色测量中,往往需要大型和复杂的仪器。然而人们对传感器的要求是必须体积小,可靠性高而且价格便宜。一种半导体颜色传感器已由sharp提出。这种传感器体积小,原理简单,而且很容易分辨颜色。在日本,冬天屋内通常用煤气加热器,煤炉加热器和石油炉。当煤气炉或石油炉在通风不良的房间中使用较长时间时,房间 I. INTRODUCTION In spectrum and color measurement, large and complex instruments are often required. However, the requirements of people on the sensor must be small, high reliability and low price. A semiconductor color sensor has been proposed by sharp. This sensor is small, simple in principle, and easily distinguishable in color. In Japan, gas heaters, coal-fired heaters and oil furnaces are commonly used in winter homes. Room when gas stove or oil stove is used for a long time in poorly ventilated room
