| 摘 要： | 设计了一种新型的叶绿素仪,以RGB颜色传感器为核心,获取叶片对测量光源的吸收率,从而得到叶绿素含量.核心传感器TCS 230将光强信号转化为方波的频率信号,利用PIC16F877a内部集成的CCP模块,采用测周期法得到方波的频率.光源系统以高亮度白色LED为光源,MAX1910为驱动,保证了测试光光强的稳定性.

| Abstract: | The new chlorophyll meter with a RGB sensor was developed.The working principle is that TCS 230 transmits light intensity into the frequency signal with chlorophyll message,and then the frequency signal is measured by CCP model of PIC16F877a.The stability of the light intensity is assured by the white LED driven by MAX1910. |
