Using Low-Cost Passive Infrared Detectors to Monitor Pig Activities in a Research Building
Low-cost Passive Infrared Detector (PID) motion sensors that provide analog outputs were permanently installed and applied for 12 years to monitor pig activities in the Swine Environmental Research Building at Purdue University.Special functions were programmed in the custom-developed data acquisition software to process the sensor signals and provide real-time, continuous, and quantitative data, which reflected the behavior-related pig activities.Measurement data using the PID sensors demonstrated substantial differences in activity magnitudes of pigs between day and night that confirmed diurnal patterns of pig behaviors.Short-time disturbance by operational work in the rooms could cause prolonged excitement and movement of the pigs.In addition, the study revealed that pigs were active at different time of the day as they grew up.The pigs were most active between 30 and 100 days of growth.The results of this study showed that the PID sensor method can be used to assist in monitoring the pig activities and living environment of livestock production and studying animal behaviors and welfare in scientific research.
