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 ...

Sonair’s 3D ultrasonic sensor enables 360° obstacle detection using acoustic detection and ranging (ADAR) for safe AMR navigation.

Originally, this parking/distance sensor used a small TFT to display the distance to an object, but after a few revisions, [Klaus] redesigned the device to speak the current distance, courtesy of ...

The first orders are already in place and the groundbreaking sensor is on track to achieve safety certification, an industry-first for 3D ultrasonic sensing in air.

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

The 12 ultrasonic sensors per car Tesla thinks it no longer needs, for example, are designed for close-range detection of other cars or objects; often thought of as "parking sensors," on Teslas ...
