The construction of a system for continuous, automatic monitoring of the activity of many animals is described. The system uses a microprocessor to control sampling of each animal box, accumulate activity scores, keep time, and control printout. For the detection units, infrared light-emitting diodes and infrared-sensitive phototransistors were used. With limited technical advice the system can be constructed by a novice of electronics. A system to monitor 40 animals would take approximately 3 wk to build and would cost about $700.
本文描述了一种用于连续、自动监测多只动物活动的系统的构建。该系统使用微处理器来控制对每个动物箱的采样、累积活动分数、计时以及控制打印输出。对于检测单元，使用了红外发光二极管和红外敏感光电晶体管。在有限的技术指导下，电子学新手也可以构建该系统。一个监测40只动物的系统大约需要3周时间来构建，成本约为700美元。
