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 ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

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, ...

AutomationDirect has added the Flowline EchoTouch, EchoSpan, and EchoSwitch lines of ultrasonic liquid level sensors and transmitters, as well as the PodView digital level indicator to their product ...

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 ...

Ultrapure or high purity water has been purified to stringent criteria to eliminate contaminants that can have an adverse effect on people, products or equipment. These can include organic or ...

AutomationDirect has added the Flowline EchoPod and EchoSonic II lines of ultrasonic liquid level sensors and transmitters to their product offerings. AutomationDirect has added the Flowline EchoPod ...
