Efficient traffic management in urban areas remains a significant challenge as vehicle density grows and infrastructure ...

The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

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 ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

With increased automation of complex production systems, components that are capable of acquiring and transmitting information regarding the production process become necessary. Proximity sensors -- ...

Ensuring safe social distancing is one piece of the puzzle for workers in the COVID-19 age. Ultrasonic range-finding sensors can measure the distance between workers with centimeter accuracy and alert ...

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 ...
