Arduino’s open-source platform makes it easy for makers, students, and hobbyists to build powerful multi-sensor projects for home automation, monitoring, and IoT applications. From motion and gas ...

I recently met Dr. Dave Horsley, CTO and co-founder of Chirp Microsystems. This is a company that was created in 2013 after incubating with Skydeck at Berkeley and the government-based SBIR program.

Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

Fans of the bouncing lamp from the Pixar corporate logo will enjoy [Daniel]’s latest project. It’s a motion controlled desk lamp that uses ultrasonic sensors to control its physical position. The core ...

For many years, one of the most common solutions for saving energy has been to “turn out the lights and dial down the thermostat.” It’s a given that unoccupied space is one of the biggest energy ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Engineers in the US have developed a fully integrated wearable ultrasound system for deep tissue monitoring that works when subjects are in motion. A wearable ultrasonic-system-on-patch for deep ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...
