For gathering information on the performance of energizer products in the field, Gallagher Group Limited had a well out-dated data-logger which periodically monitored the voltage of the fence and transmitted the data back to base over a GSM network. However the existing data-logger had very limited capability and a new one was needed that could monitor the environment inside and around the energizer, and hopefully provide some information on why an energiser might be failing.The ideal data-logger was self powered, could last years in the field without needing to be serviced, and could collect data on the energizer without affecting it in any way. It would also collect data on as many environmental parameters as possible, such as temperature, humidity, ambient light level, lightening strikes and pressure. Ideally it would also be able to monitor the energizer voltage using a contactless measuring system.The data-logger was designed for Gallagher Animal Management Systems, the part of Gallagher Group Limited that specialises in farming equipment. The design project arose from the need for a data-logger that could monitor both the fence voltage and the environment around the fence, so that a critical explanation of why an energizer failed in the field could be found, leading to better product design in the future. It was jointly funded by Gallagher Group Limited and the Foundation of Research Science and Technology (FoRST).
