Designing a low-cost, simple-to-install study instrument that can be utilized in group-housed animals is critical for quantifying elements needed to assess animal health and well-being. This research aimed to develop a non-invasive, easily deployable continuous tympanic heart rate and core temperature detecting prototype system capable of recording and transmitting data from a group of hair sheep cattle. The data were gathered in 60 ewes over three hours, with readings every 15 minutes. At the same time, a commercial sensor was used to monitor vaginal temperature, as well as an electrocardiograph, was employed to assess heart rate. The results revealed a positive correlation between the heart rate and the electrocardiograph, but the correlation between the layer tamponade and the vagina was negative.
