A low-cost, do-it-yourself data-logging system to record animal activity in laboratory and small-enclosure experiments

Abstract

With the increasing cost of prepackaged research equipment and restrictions on research budgets, there is a growing need for inexpensive solutions for data collection in laboratory and small enclosures across a range of research topics investigating responses of animals to experimental parameters. We present here a low-cost, modular passive infrared sensor and data-logging system for use in experiments evaluating animal activity and behaviour, easily assembled in a laboratory setting. This system comprises accessible kit-based components purchased from popular electronics suppliers. We present the hardware configuration, software coding, build of materials, circuit diagram and a sample dataset demonstrating that the system collects reliable data that is easily downloaded either through any terminal program, directly from the unit or via an SD card. It is hoped that this ‘freeware’ approach to activity-monitoring equipment will enable laboratory and enclosure-based research to be undertaken more cost-effectively.
