Passive infrared (PIR) detection capability refers to the degree to which a sensor can reliably identify movement based on changes in infrared radiation levels within its field of view. For example, a higher level of this detection capability enables a security system to distinguish between the movement of a small animal and a human, thus reducing false alarms.
The functionality is essential for various applications, ranging from security systems to automated lighting controls. Its importance lies in the ability to provide accurate and energy-efficient monitoring of spaces. Historically, development has focused on improving the range, accuracy, and noise reduction within these sensors to minimize errors and enhance operational performance.
