Description

This report covers the theoretical design and implementation of a Data Logging device. The report aims to highlight the design stages undertaken from initial conception through to the testing of the end product constructed. The design was initiated in order to aid conservationists in researching the living conditions of bats. Thus the procedure which was adopted to create a cost effective and user-friendly device can be clearly seen, in the report, as the system is developed. The data logger created stores hourly samples of temperature and humidity data for a period of 6 months. In order to allow the system to operate off batteries low power consumption was an important criterion in the design process. The device allows the user to download the stored data to a PC via the USB port. PC software has also been created that will enable the user to view the data in a suitable format. Due to the environment in which the device will have to operate a robust housing was created. The system created was also tested and the results of these tests have also been included in the report as well as a detail analysis of the design which highlights areas of improvement.
