This project uses an Arduino Uno, an ultrasonic sensor, and an LCD to create a water level indicator. The ultrasonic sensor measures the water level in a tank and displays the percentage of the tank's ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

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 ...

The automation of height-increasing bridges during floating events is a crucial engineering challenge in areas prone to flooding or water surges. It proposes a solution to adjust the bridge height ...
