But can we extend the capabilities of a $5 ESP32-CAM module to build something similar? In this project, we are going to build an AI-Based No Parking Alert System using ESP32-CAM, in which, if someone ...

Why passive ultrasonic offers a unique option of sensing discrete open/close events. How a team used passive, non-electronic metal tag for signal initialization. How they used DSP-based, non-ML, ...

Looking ahead: Midjourney built its name on AI-generated images. Now, it is talking about something far more ambitious: scanning the human body. In a post this week, the company outlined plans for a ...

Winnebago County Public Health has launched a new program to monitor local air quality. The initiative uses real-time sensors and a color-coded flag system to inform residents. Flags indicate air ...

Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using only sound. Without electricity, electronics, or batteries. The sensors are ...

In the era of A.I. agents, many Silicon Valley programmers are now barely programming. Instead, what they’re doing is deeply, deeply weird. Credit...Illustration by Pablo Delcan and Danielle Del Plato ...

A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

I tried a techy new knife at CES 2026. Here's my take on whether this pricey blade is worthy of the hype. We’re tracking all the latest news out of CES, and one of the buzziest drops is a knife that, ...

You brush your teeth, floss regularly and faithfully wear your retainer every night. But despite your diligent oral health habits, your retainer or mouth guard can get yellowed, cloudy or stained.

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...
