Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and provide an instant audible alert to them. So they can navigate independently. The best part of this blind ...

Enables autonomous driving of a 2 or 4 wheel car with an Arduino and a Adafruit Motor Shield V2. To avoid obstacles a HC-SR04 Ultrasonic sensor mounted on a SG90 Servo continuously scans the area.

Or, you can buy an ultrasonic cleaning machine and let it do all the work instead. These countertop contraptions—which we have not tested—claim to dislodge food bits, bacteria, and the like ...

Deepen AI's patented approach automates and optimizes sensor calibration, setting new industry standards for accuracy and efficiency. "Our system level technology eliminates guesswork in sensor ...

HAL-based driver for the HC-SR04 ultrasonic sensor, implemented on an STM32F446RE Nucleo board. Key features include temperature-compensated distance calculation, pulse width validation with hardware ...

Ultrasonic sounds are high-frequency sound waves that exceed 20,000 hertz, making them too high-pitched for human ears to detect. These sound waves vibrate more than 20,000 times per second. Doctors ...

Abstract: Calibration is a costly, necessary part of sensor manufacturing. Bayesian sensor calibration leverages prior knowledge in the form of a sample of sensor response functions from a sensor ...

Now, a new generation of small, roaming air sensors could better inform people about pollution levels in their local area. Currently, these sensors just aren't precise enough. Our recent research ...
