Ultrasonic sensors use sound waves above 20 kHz to measure the distance from the sensor to a specified target. The sensor transmits and receives sound via a ceramic transducer that acts like a ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

A new category of sensing technology transforms mobile robot vision from 2D to 3D, improves safety performance and provides 50-80% cost savings compared to traditional, LiDAR-based systems and sensor ...

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 ...

A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track ...

Qualcomm has just announced the 3D Sonic Sensor Gen 2, the latest version of its ultrasonic in-display fingerprint sensor that looks to improve on the original model in nearly every way. The new ...

Tesla has spent years arguing that a camera‑centric approach to driver assistance can match or surpass the performance of rivals that lean on ultrasonic sensors and radar. The company’s latest ...

Weather stations are a popular project for experimenting with various environmental sensors, and for wind speed and direction the choice is usually a simple cup anemometer and wind vane. For [Jianjia ...

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 ...
