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 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 ...

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 ...

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 ...

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 ...

What is the HC-SR04? HC-SR04 is an ultrasonic ranging sensor that provides 2 cm to 400 cm non-contact measurement function. Is the HC-SR04 accurate? The ranging accuracy can reach to 3mm and effectual ...

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eBay ...
