Tips: Human Presence Sensors vs. PIR Sensors

In the field of intelligent sensing, human presence sensors and traditional pyroelectric infrared (PIR) sensors differ significantly in technical principles and application performance. The former uses millimeter-wave radar for active detection, accurately recognizing regular movements and micro-motions like heartbeat/breathing. It operates stably amid ambient temperature fluctuations, heat/light/airflow interference, penetrates insulating materials (fabrics, plastics, glass), and supports 0~6m ranging. In contrast, PIR sensors rely on passive infrared sensing, only detecting short-range human movement. They suffer from reduced sensitivity due to environmental factors and lack ranging/penetration capabilities, making human presence sensors more accurate and reliable for diverse intelligent sensing needs.
