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 ...

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 ...

Low Water Level: The first LED illuminated when the charge time was less than 10800 microseconds. Medium Water Level: The second LED illuminated when the charge time was between 10900 and 11250 ...

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.

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 ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

The water level indicator project utilizes an Arduino Uno microcontroller, an LCD display, and a Bluetooth module to provide an efficient solution for monitoring water levels and controlling a motor.

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.
