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 ...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle-avoidance and distance-measurement systems. The ultrasonic range finder measures the ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...
