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 ...

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 ...

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 ...

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 ...

In-display fingerprint sensors have become commonplace in virtually all Android smartphones, for better or for worse, and five years later we’re finally seeing the ultrasonic variety widely used by ...

Sonair is pushing towards a new sensor built on 3D ultrasonic technology, giving autonomous robotics the power to see and make the right decisions. Ralph W. Bernstein is the senior business developer ...

Ultrasonic close-range sensors have joined radar in the trash bin over at Tesla, which going forward will build its cars with only cameras onboard to power its driver assistance and collision ...

Machines are moving beyond single-point sensing. Multi-sensor fusion now delivers vision, ranging and inertial data. The ...
