Distance Measurement using HC-SR04 and 16x2 LCD with 8051 Microcontroller Overview This project demonstrates how to interface an HC-SR04 Ultrasonic Sensor and a 16x2 LCD with an 8051 microcontroller ...

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 ...

This project uses an Arduino microcontroller with an HC-SR04 ultrasonic sensor to measure distances. The Arduino emits ultrasonic pulses and measures the time it takes for the echo to return. This ...

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 ...

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 ...

If you want to play with radar — and who could blame you — you can pretty easily get your hands on something like the automotive radar sensors used for collision avoidance and lane detection. But the ...

Makers, developers and enthusiasts building distance related projects may be interested to know that the HC-SR04 ultrasonic sonar distance sensor is now available to purchase directly from the ...
