The Ring Spotlight Cam Pro (2nd Gen) reviewed here is a plug-in model, available in white or black. Ring also offers a hardwired version for $308.98, or a Power over Ethernet (PoE) model for $319.98.

This project shows a super easy way to get started with your own DIY Multisensor to use with Home Assistant, a sick, open-source Home Automation platform that can do just about anything. This code ...

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 ...

Abstract: In this paper, we use a modified passive infrared radiation or pyroelectric infrared (PIR) sensor to classify 5 different human motion events with one additional “no action” event. Event ...

Abstract: Passive infrared (PIR) sensors are widely used in motion sensing and lighting control. However, stationary occupants always trigger false-negative detects of PIR sensors and result in ...

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 ...

Wheel bearing and ABS sensor tolerances can trigger ABS codes and erratic signals. Learn key diagnostic steps for accurate ...

Here we are designing a very small, tiny CAN network sensor that can be attached to any vehicle. It detects motion, accidents, and all vehicle activities in real time. It can also be modified to act ...
