In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

In recent years, the demand for smart security and automated monitoring systems has increased significantly due to growing safety concerns and the need for real-time surveillance. Traditional security ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Panasonic Industry unveils a new generation of passive infrared (PIR) motion sensing arriving with a clear message: performance no longer needs to come at the cost of design. A recently introduced ...

Aqara is introducing a new presence sensor that is a natural addition for HomeKit users who want reliable automations without the need for a camera. The new Aqara FP300 combines mmWave presence ...

Northwest U.S. utility Puget Sound Energy (PSE) has joined with Norway-headquartered Heimdall Power on a dynamic line rating (DLR) pilot project in Washington state. The companies on October 22 said ...

Qualcomm wants to expand accessibility to its technologies, and its next step in that mission is buying popular open-source computing company Arduino. The platform, popular with tech hobbyists for ...

In addition to knowing if a neighborhood is experiencing active flooding, it helps to have a bit more data. How regularly do these events occur? Is flooding expected based on the forecast? “The sensor ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

ABSTRACT: 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.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
