This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD.

About This project uses an Arduino Uno and an HC-SR04 ultrasonic sensor to measure the distance of nearby objects and display it on a 16x2 LCD. If an object is too far, it shows “Seems safe...” on the ...

Vehicle over-speed detection and accident-avoidance system is an Internet of Things (IoT) based system which collects data via sensors such as ultrasonic sensors and alerts the driver. The sensor is ...

In technological developments, ultrasonic sensors are often used to measure the distance from an object. The ultrasonic sensor commonly used to measure distance is the HCSR04 ultrasonic sensor. The ...
