| Abstract: | We design a signal acquisition system for the detection of the content of soil organic matter, which is based on a single chip microcomputer (SCM). Its core chip is ATmega16 and optoelectronic conversion module is a HAMAMATSU made photomultiplier. It communicates with a PC through a RS-232 serial interface. Experiments show that the system is reliable and satisfies the design requirements. |
