主要介绍自制的基于光寻址电位传感器(LAPS)的生化检测仪。文中概述了LAPS的基本原理,并介绍了LAPS弱信号检测仪表的硬件与软件设计。仪表采用AT89C52单片机与PC机进行标准串接口通讯,具有灵敏度高,成本低,易维护及能进行多参数测量等特点。同时利用该检测仪表进行了pH值等参数的测量。
The main introduction of homemade light-based addressable potential sensor (LAPS) biochemical detector. This paper outlines the basic principle of LAPS, and introduces the hardware and software design of LAPS weak signal detection instrumentation. Instrument using AT89C52 SCM and PC for standard serial interface communication, with high sensitivity, low cost, easy to maintain and can carry out multi-parameter measurement and so on. At the same time using the instrumentation for pH and other parameters of the measurement.
