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 ...

[Emil] got his hands on a dozen HC-SR04 ultrasonic sensors, but wasn’t too happy with their performance. Rather than give up, he reverse engineered the sensor and built an improved version. Hackers, ...

This homemade parking sensor was developed using an Arduino, ultrasonic range finder and some other components to guide vehicle parking. One of the main materials used is the Arduino duemilanove which ...

We are currently in the process of putting in a backyard pool. This is an in-ground gunite pool. I inquired about an auto-fill system from the pool builder but he talked me out of it. He explained ...

Makers, hobbyists and Arduino enthusiasts searching for a new project to keep them busy, may be interested in this awesome Arduino range measure and digital spirit level project created by Dejan ...

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 ...

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 ...

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 ...
