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 ...

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, ...

Serial Kickstarter entrepreneur Patrick Thomas Mitchell has once again taken to Kickstarter to raise funds to take his new programmable Arduino ultrasonic experiment kit into manufacture. Once ...

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 ...

Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

Arduino’s open-source platform makes it easy for makers, students, and hobbyists to build powerful multi-sensor projects for home automation, monitoring, and IoT applications. From motion and gas ...

[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]’ ...
