📋 目次
1What detection range should I look for in a PIR motion sensor?
Most PIR sensors offer a detection range of 15-30 feet, with some models extending up to 50 feet. Look for a sensor with a wide horizontal field of view (typically 100-120 degrees) and adjustable sensitivity to avoid false triggers from small movements like pets or drafts.
2Do PIR motion sensors work through glass or walls?
No, PIR sensors detect motion through infrared heat signatures and cannot see through solid objects like glass, walls, or doors. For outdoor use, ensure the sensor has a clear line of sight to the area you want to monitor, and avoid placing it behind obstructions.
3What’s the difference between passive and active PIR sensors?
Passive PIR sensors detect infrared radiation from moving objects without emitting any signals, making them energy-efficient and ideal for home use. Active PIR sensors emit a signal and detect its reflection, offering greater accuracy and range, but they are more expensive and typically used in industrial or security applications.
4How long do PIR motion sensors last, and what affects their lifespan?
PIR sensors typically last 5-10 years, depending on environmental factors like humidity, temperature, and exposure to dust. Units with adjustable sensitivity and a built-in filter to reduce false alarms tend to perform better over time and require less frequent replacement.
5Are wireless PIR motion sensors reliable for home security systems?
Wireless PIR sensors are reliable when paired with a strong, secure signal and a compatible receiver. Look for models with low-power consumption and a range of at least 100 feet. Ensure your system includes a backup power source or battery backup to maintain functionality during outages.
