This project demonstrates an Automatic Water Level Controller using an Arduino Uno, HC-SR04 ultrasonic sensor, a relay module, and two push buttons. The ultrasonic sensor measures the distance from ...

Connect the Components: Follow the circuit diagram to connect the water sensor, LED, and Arduino. Upload the Code: Open the Arduino IDE. Copy and paste the provided code into the IDE. Select the ...

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.

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 ...
