March 5, 2026 – Dallas, TX – TI Expands Analog Portfolio Texas Instruments today announced the PGA460, a dedicated signal conditioning integrated circuit for pyroelectric infrared sensors. The new IC combines all the analog front-end components needed for PIR sensors…
March 8, 2026 – Tokyo – Breakthrough in Flexible Pyroelectric Sensors A research team at the University of Tokyo’s Institute of Industrial Science has demonstrated a flexible, thin-film PIR sensor that can be integrated into clothing, bandages, and wearable devices.…
March 10, 2026 – Wrocław, Poland – Panasonic Expands European Manufacturing Footprint Panasonic Corporation today officially opened its new €150 million PIR sensor manufacturing facility in Wrocław, Poland. The plant will produce high-sensitivity PIR sensors for the European building automation,…
March 12, 2026 – Brussels – EPBD Update Passes with Bipartisan Support The European Parliament has approved the latest update to the Energy Performance of Buildings Directive (EPBD), mandating occupancy-based lighting and HVAC control in all new commercial buildings starting…
March 15, 2026 – Honeywell Expands Sensor Portfolio with Strategic Acquisition Honeywell International announced today the acquisition of SenxTech, a Silicon Valley-based startup specializing in AI-enhanced PIR sensors, for $450 million in cash. The deal is expected to close in…
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…
Introduction Rapid ambient temperature changes are a common but often overlooked cause of PIR sensor false triggers. When an HVAC system kicks on, a door opens to the outside, or a large appliance cycles, the sudden temperature shift can be…
