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 ...

If an object is detected in the 180-degree field of view of the sweeping sensor, ... Inside the 3D printed enclosure is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, ...

If you want to play with radar — and who could blame you — you can pretty easily get your hands on something like the automotive radar sensors used for collision avoidance and lane detection ...

Each sensor constantly scans the environment using ultrasound to detect anything closer than 60 feet. As an object moves near, the sensor sends a message to a controller box that calculates the ...

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 ...
