Every smart home owner is likely to be familiar with “passive infra red” (PIR) motion sensors as they’re an easy way to start off making a home a little smarter They’re quite distinctive too, with the ...

You'd think a remote control technology that was first introduced in the 1980s would be completely obsolete by now. But infrared (IR) remotes are still very much kicking half a century later, despite ...

The infrastructure of the site is designed to facilitate rapid expansion of production. Credit: © L3Harris Technologies, Inc. L3Harris Technologies has initiated the ...

Murata SMD TYPE IRS-D200ST00R1 is one of the world’s smallest PIR motion sensors at just 6 x 6 mm in size and with a 2.6 mm thickness. Its name implies, it’s a reflowable SMD component, which ...

The XIAO Smart IR Mate is a compact circular-shaped IR remote hub/blaster built around the XIAO ESP32-C3 and designed for IoT applications. It comes pre-flashed with ESPHome and turns traditional ...

On my machine, the realsense-viewer works without any issues. In the viewer, I'm able to see depth image, RGB image, as well as Accelerometer and Gyroscope data. However, when I try to access the IMU, ...

An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...

Abstract: This research work describes the design and application of an automatic train detection and gate control system using the ATmega328P microcontroller and Passive Infrared (PIR) motion ...

This study investigates the optimization of Fresnel lens designs using Zemax software, with a focus on minimizing beam divergence by controlling the output spot diameter on the image plane. Global and ...
