Automatic Plant Watering System using Arduino Uno .
Hey, I'll show you how you can make an automatic water irrigation system USING Arduino for your home garden or any potted plant. For this, you will need one Arduino, one 5-volt relay module, one small water pump with a tube of around two feet, one soil moisture sensor, and a few jumper wires. You can get all those components from your local market, or you can check out the link given in the description. Now let's program the Arduino, then we'll continue with the connections.Here, as you can see,
I have connected both the pins of the soil moisture sensor with the main control board. Then the VCC pin of this main control board will be connected to 3.5 volts of the Arduino, the ground pin will be connected to the ground pin of the Arduino, and the DO pin, that is the digital output pin, will be connected to pin number 6 of the Arduino.
Now let's connect the relay module and the water pump. Here, as usual, the VCC pin of the relay module will be connected to 5 volts of the Arduino.
The ground pin will be connected to the ground pin of the Arduino. And the IN pin will be connected to pin number 3 of the Arduino.
Then, on the other side of the relay module, one terminal of this 5V supply will be connected to the common pin of the relay module.
And the other will be connected to the NO pin, that is the normally open pin of the relay module, through this water pump, as you can see here in the connections.
So basically, the concept behind this project is it will take care of your plants in your absence.
Whenever there will be a shortage of water in your garden or potted plants, then the soil moisture sensor will send a signal to the Arduino, and the Arduino will send a signal to the relay module. Then this water pump will be activated and irrigate your garden or potted plant. Then, as soon as it reaches the desired saturation level, it will automatically get disconnected so that your plants remain healthy.
