This project measures the distance of an object using an HC-SR04 Ultrasonic Sensor and displays the result on a 16x2 I2C LCD. 📷 Demo (What It Does) Sends ultrasonic pulses from the sensor. Calculates ...

The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

Abstract: Ultrasonic sensors (US) are widely used for detecting objects in different application areas such as parking sensors in automobiles, assisting in UAV navigation etc. In our current work, we ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

Abstract: Obstacle detection (OD) techniques for collision avoidance applications in automobiles and unmanned aerial vehicles have been of research interest in the recent years. This technical idea is ...

A salvaged Tesla Model 3 could detect distances even after the front bumper containing the ultrasonic sensors was taken off. This finding is surprising considering that the car was running the 2022.28 ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil was left in ...
