Remote sensors on livestock is one of those things that in 1984 you would have thought impossible- and today- we're almost spoilt for choice. But, like any technology, how much further can we take it and what is it's potential? Mark Trotter is a researcher leading Central Queensland University's Precision Livestock Management team. His specialist area is the development and evaluation of on-animal sensors, such as smart tags, to improve monitoring and management of individual animals for production, health and welfare issues. In this episode he talks about the benefits and the challenges of remote sensors and how CQU is leading the charge in research for grassroots applications.
