The beginner’s guide for hobbyists and makers unlocks some of the practical secrets behind lightning detection design.

Create a smart blind stick using Arduino to help visually impaired individuals navigate safely. This DIY project uses an ultrasonic sensor, buzzer, and LED indicators to detect obstacles and provide ...

Two papers at the International Solid-state Circuits Conference tackled ultra-low power on-chip temperature sensing, one using an npn transistor and the other by sensing a wire. The npn sensor ...

The trick to creating a better quantum sensor? Just give it a little squeeze. For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing ...

For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

A new category of sensing technology transforms mobile robot vision from 2D to 3D, improves safety performance and provides 50-80% cost savings compared to traditional, LiDAR- ...

The ultrasonic sensor uses sonar to determine the distance to an object. Here’s what happens: The ultrasound transmitter (trig pin) emits a high-frequency sound (40 kHz). The sound travels through the ...

Google's Pixel 9 series will feature an ultrasonic under-display fingerprint sensor, letting go of the suboptimal optical sensor for good.

An ultrasonic fingerprint scanner should make unlocking faster and more reliable. With the Pixel 9, Google is finally making the switch to an ultrasonic fingerprint scanner.

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...
