Microcontrollers for Kids shows a classroom-tested path from Scratch to Open Roberta to Arduino UNO, with printable coding ...

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 ...

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

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 ...

A complete home automation system developed on ESP32 microcontroller using freeRTOS. The system is controlled wirelessly via Bluetooth with an android app developed using MIT App Inventor. This ...

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 ...

The 420B and 412B series of ultrasonic sensors from Leuze are available with an adjustable sound cone and as switching (HTU) or measuring (DMU) sensors allowing for flexible application. The sound ...

The Google Pixel 9 series is here, and one of the biggest upgrades it delivers is the use of a new ultrasonic fingerprint sensor, and it’s the same one used in Samsung Galaxy devices. In the “Tensor ...

Following user frustrations with the under-display fingerprint sensor introduced on the Pixel 6, Google appears to be making a change with the Pixel 9 series. According to a report by Android ...

Valeo has been granted a patent for an ultrasonic sensor designed for vehicle distance detection systems. The sensor can be installed with others, receiving and modulating data signals through supply ...
