This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, ... the voice is set up to speak the distance from an object to the sensor from 10 cm to 1 m in 5cm increments.

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 ...

In contrast, Sonair’s patented ADAR (acoustic detection and ranging) technology detects people and objects in 3D. A single ADAR sensor provides a full 180 x 180 field of view (FoV), and a 5 ...
