Introduction Moving water can be a surprising source of false triggers for PIR sensors. Whether from decorative fountains, swimming pools, sprinkler systems, or rain, water in motion creates changing IR patterns that can mimic human movement. How Moving Water Causes…
Introduction PIR sensors detect the difference in infrared radiation between a warm object (like a person) and the background. When ambient temperature approaches human body temperature (35-37°C), this difference becomes very small, making detection difficult or impossible. The Physics Behind…
Introduction Radio frequency (RF) interference is an increasingly common cause of PIR sensor false triggers as the number of wireless devices in homes and businesses continues to grow. Wi-Fi routers, cellular phones, radio transmitters, and even smart meters can all…
Introduction Standard glass is opaque to the 8-14µm infrared radiation that PIR sensors detect. This is a fundamental limitation of the technology. However, there are scenarios where detecting through a window is necessary. This article explores advanced solutions. Why Standard…
