The integration of Passive Infrared (PIR) motion detection devices in ghost detection emerged with the advent of technological advancements in paranormal investigations.
PIR sensors, commonly utilized in security systems and automation, detect changes in infrared radiation emitted by objects within their field of view.
In the context of ghost hunting, these devices were repurposed to identify anomalous movements or changes in thermal energy that could signify the presence of an otherworldly entity.
Ghost hunters began deploying PIR motion sensors in haunted locations, believing that these devices could detect unexplained fluctuations in temperature or movement that aligned with reported paranormal activity.
