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 ...

Lady of Shallott is a DIY analog water sensor using Arduino and Max/MSP. The analog read from Arduino went into Max/MSP, which then looped through specific frames when the doll head raises the water ...

Circuit Fig. 3 shows the circuit diagram of the automatic water level indicator cum controller. It is built around an Arduino Uno board (MOD1), three LEDs, a 5V SPDT relay, and other components. First ...

Automatic Plant Watering System Block Diagram The below block diagram gives us a clear view of how this automatic plant watering system will work. Basically we have the Arduino Uno R4 which will read ...

The basic design idea is to set two ports of the MCU for water level detection, one port for automatic/manual mode switch selection, and two ports for visual status indication. From the reading of the ...

For additional water quality information, the device also has an Arduino Nano connected to pH, TDS (total dissolved solids), and water temperature sensors which then are fed to the Pi via a serial ...

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 sensor was ...

There are a flame sensor and a water pump up forward, as well. You can probably guess, the device notices a flame and rushes to squirt water on it. That got us thinking, though.
