How to Water Your Plant with Arduino Pump

Maintaining a healthy plant can be a difficult task, especially if you are not always around to water it. Luckily, with the help of an Arduino pump, you can automate the watering process and ensure your plant stays hydrated, even when you are not home. In this article, we will walk you through the step-by-step process of how to water your plant with an Arduino pump.

What You Will Need

To get started with this project, you will need the following materials:

Arduino Uno

Breadboard

Peristaltic pump

Waterproof temperature sensor

Jumper wires

Power supply (such as a 9V battery)

Plastic tubing

Building the Circuit

To build the circuit, start by connecting the peristaltic pump to the Arduino Uno. Connect the positive wire of the pump to pin 7 on the Uno and the negative wire to GND. Next, connect the waterproof temperature sensor to the Arduino. Connect the positive wire to 5V, the negative wire to GND, and the data wire to pin 2. Finally, connect the power supply to the breadboard and connect the Arduino to the breadboard and power supply. You should have a completed circuit that looks something like this:

Creating the Code

Now it’s time to create the code for your Arduino pump. The basic idea of the code is to pump water to your plant when the temperature sensor detects that the soil is too dry.

Start by defining the pin numbers for the pump and temperature sensor in your code. Then, create a variable for the desired moisture level of the soil. This will determine when the pump should be activated. You can adjust this value to fit the needs of your plant.

Next, create a loop that reads the temperature sensor’s data and checks if the soil moisture is below the desired level. If the moisture level is below the desired level, the pump will be activated, and water will be pumped to your plant. Finally, add a delay to the loop to ensure that the code doesn’t constantly loop and over-water your plant.

Testing the System

Before you begin using the system, it’s important to test that everything is working correctly. Place the waterproof temperature sensor in the soil of your plant and turn on the system. Wait a few minutes to give the pump time to activate, and check that water is being pumped to your plant. If everything is working correctly, congratulations! You now have an automated watering system for your plant.

Conclusion

Watering your plant no longer needs to be a chore thanks to the help of an Arduino pump. With just a few materials and some basic programming skills, you can create an automated watering system for your plant that will keep it healthy and hydrated, even when you are not around. Happy planting!
