A real-time ultrasonic radar system built using Arduino Uno, HC-SR04, SG90 Servo Motor, and Processing. The project scans objects using an ultrasonic sensor mounted on a servo motor and visualizes ...

All [Hannah Robertson]’s Birduino needs is for one to tap an NFC-enabled card to the reader, and the device plays one of the vocalizations associated with the bird shown on the card. It ties together ...

Ayush Pande is a PC hardware and gaming writer. When he's not working on a new article, you can find him with his head stuck inside a PC or tinkering with a server operating system. Besides computing, ...

Multifunctional structural metals capable of monitoring their internal mechanical state are increasingly important. Here multilayer strain sensing architectures are embedded directly within Ti-6Al-4V ...

Ultrasound is a non-invasive imaging technique that uses the differential reflectance of acoustic waves at ultrasonic frequencies to detect objects and measure distances. It is commonly used for ...

Emerging air quality sensors – with general traits of being more compact, directly reading pollutants, and lower in cost than traditional methods - have a wide appeal to professional researchers, ...

Sensors and Diagnostics is a gold open-access journal publishing innovative and high-impact research on sensing technologies and diagnostic systems. The journal focuses on studies that explore novel ...

There has been a dramatic increase in the use of air sensors to measure air quality, however, it is widely known that sensor data quality is highly variable. The lack of consistent testing protocols ...
