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 ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

In an interview with pv magazine, cybersecurity expert Mohammad Al Faruque explains how seemingly simple sensors in PV systems and other energy systems are surprisingly vulnerable to magnetic, ...

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost ...

Say goodbye to embarrassing parking mishaps. Whether you’re after added peace of mind during close-quarters maneuvering of your car or truck or you share a vehicle with a younger or less-experienced ...

Exceptional points (EPs) in non-Hermitian systems offer a strong response to perturbations, offering a promising platform for sensing. By using a third-order EP of coherent perfect absorption, here, ...
