Recent advances made in the automotive world have found an unlikely application: a new high-performance portable lantern. And ...

Abstract: The rapid expansion of the Internet of Things (IoT) necessitates unprecedented resource efficiency in sensor-edge hardware to implement artificial intelligence (AI). A memristor-based ...

Passive infrared (PIR) sensors are experiencing sustained growth in 2026. This is driven largely by the expansion of smart home technology, building automation, and energy-conscious design. Once ...

Abstract: The spatio-temporal sequence of human body movements provides important information about daily action patterns. This article presents a pyroelectric infrared (PIR) sensor array for ...

This is a simple project in which a HC-SR501 PIR sensor is used to detect motion in a room. MQTT is used as the message broke between NodeRed and Rust running on a Raspberry Pi 4. The code detects the ...
