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 ...

Objective To create an efficient water level monitoring system using an HC-SR04 sensor and Arduino, enabling real-time data collection, visualization, and potential IoT integration for various ...

The TDS sensor detects water conductivity. The Arduino reads this analog signal and converts it to digital. A calibrated formula calculates the TDS value in ppm. The LCD displays the real-time TDS ...

Abstract: We connected $\mathbf {p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...

Water and energy are two critical issues in the global sustainable development of this new century. The proposed design is a very simple implementation with low cost, which automated the water pump ...
