Abstract: This paper presents a novel approach to dynamically adjust the sensitivity and timing parameters of a Passive Infrared (PIR) motion sensor using an Arduino-based control system. Traditional ...

Abstract: Pyroelectric infrared (PIR) sensors are much promising for device-free localization (DFL) due to their advantages of lower cost, low power consumption, and privacy protection. Most PIR-based ...
