DIY Plant Watering System for a Greener Garden

Creating a DIY plant watering system can be a game-changer for gardeners, especially during dry spells. This system can be made using a variety of materials, including PVC pipes, fittings, and a water reservoir.

To start, you'll need to determine the water requirements of your plants, which can be found in the section on "Calculating Water Needs". This will help you design a system that delivers the right amount of water at the right time.

A key component of a DIY plant watering system is the water reservoir, which can be made from a large container or a plastic barrel. This reservoir will hold the water that's dispensed to the plants, and its size will depend on the number of plants and their water requirements.

By automating the watering process, you can ensure that your plants receive the right amount of water, even when you're not around to water them.

A DIY plant watering system is made up of several key components, each playing a crucial role in ensuring your plants receive the right amount of water.

The water reservoir is a vital part of the system, holding the water that will be distributed to your plants. It's typically made of a waterproof material, such as plastic or metal.

A float valve is used to control the water level in the reservoir, automatically shutting off the water supply when the level is reached. This helps prevent overwatering and ensures the system runs efficiently.

The tubing and fittings are used to distribute the water from the reservoir to the plants. Picking the right size and type of tubing is essential to ensure the water flows smoothly and reaches all the plants.

A drip irrigation system is often used in DIY plant watering systems, delivering water directly to the roots of the plants. This helps reduce evaporation and runoff, making the system more water-efficient.

The timer is used to schedule when the system turns on and off, allowing you to control the watering schedule according to your plants' needs. This can be set to water your plants at specific times of the day or week.

You can control your DIY plant watering system from the comfort of your home or even remotely, which is super convenient. This is made possible by using a smart relay, such as the Shelly relay, which allows you to turn the system on or off directly from the Shelly app.

To improve connection stability, it's a good idea to give your smart relay a fixed IP address, which can be done by opening the app, choosing your device, and going into Networks, Wi-Fi 1, and setting a static IP address.

Programming your DIY plant watering system is also a crucial step, and it's recommended to upload the source code before proceeding to the circuit connections. This will prevent any damage to your computer if you're using a USB connection to program the board while the water pump motor is connected to the circuit.

To install a solenoid valve, you'll want to choose a normally closed brass solenoid valve that runs on 230v, such as the one mentioned in the article.

This type of valve has a great advantage for safety, as it will shut off the water immediately if the power fails during irrigation.

To connect the valve, use a three-wire cable and follow the instructions for connecting the ground, neutral, and line wire to the power connector on the side of the valve.

The valve should be tested by temporarily connecting it to a water hose and turning the power on and off to ensure it's working correctly.

Before installing the solenoid valve, consider putting a filter before it to prevent impurities from clogging the irrigation system.

The filter should have a net inside to trap impurities, and can be cleaned by unscrewing the cap.

To connect the filter to the solenoid valve, use a fitting with teflon tape on the thread to make a secure joint.

You can also use a flexible metal pipe to connect the water output of the solenoid valve to the plastic irrigation pipes.

To attach the solenoid valve to the wall, use a 3D printed bracket and a wall anchor, as shown in the .stl file provided.

A smart relay, such as the Shelly Pro 1, is needed to connect the solenoid valve to home automation and control it remotely.

The smart relay should be mounted on a small electrical panel with a DIN rail, and connected to the solenoid valve using two pieces of wire with ferrules.

The neutral, line, and ground wires should be joined together with clamps to complete the connections.

Finally, the smart relay should be configured using the app on your phone, following the instructions provided with the device.

You can control the valve from the app, which is super convenient. The Shelly app allows you to turn the plant watering system on or off directly from the app, either locally or remotely.

To improve connection stability, consider giving your smart relay a fixed IP address. This is a good idea, especially if you're using a Shelly relay.

The Shelly app also lets you set the times at which to water automatically, which is really helpful for busy people. To do this, simply click on the device's name and on Schedule.

This level of control is especially useful when you're on vacation and can't be there to water your plants. With the app, you can turn the system on or off remotely, so you can relax knowing your plants are being taken care of.

Before uploading the source code, make sure your computer is not connected to the circuit with the water pump motor, as this may damage your computer.

You can use any Arduino model or the 2 in 1 board, and the source code is compatible with both.

To upload the code, you'll need to select the BOARD option in the Arduino IDE editor, which should be set to Arduino UNO for the 2-in-1 board.

If you're using a different Arduino model, choose the board that matches your model, such as UNO, Nano, or Mega.

To download the Arduino IDE editor, visit https://www.arduino.cc/en/software.

Connecting your water pump to the Arduino board is a crucial step in getting your project up and running. The board I designed includes a built-in L293D motor driver, which makes connections much easier.

To connect your water pump, you'll need to know the voltage range it operates on. Typically, a 6V-12V water pump has two pins: a negative (-) pin and a positive (+) pin. The negative pin needs to be connected to the OUTPUT1 pin of the L293D motor driver.

The positive pin, or the red wire, needs to be connected to the OUTPUT2 pin of the L293D motor driver. If you're using a 7.4V-9V power supply, the positive pin needs to be connected to the VS pin of the L293D motor driver, and the negative pin needs to be connected to the GND pin.

Here's a summary of the connections you'll need to make:

7.4V-9V power supply:

Remember to keep the power supply separate from the microcontroller to avoid damaging the board.

A DIY drip irrigation system is a great way to keep your plants watered while you're away. All you need is a two-liter plastic bottle, a lighter, a pin, a small stake or skewer, and some tape.

You can also make a DIY drip hose from an old hose you might otherwise toss into the trash. Punch tiny holes in the hose, leaving 6 inches with no holes on both ends, and attach a hose cap to one end. Attach the other end to another hose that's long enough to reach from a spigot to your garden.

A 50-ft. drip hose costs $14 at big box stores, but making one yourself can be a fun and cost-effective project. To make a drip hose, you'll need an old hose, an upholstery needle or a tiny drill bit, a hose cap, and another hose to attach to the end.

You can also use a wicking system to water your plants. This involves laying a string or shoelace in a container of water and burying the other end in the soil of a container plant.

Here are some DIY irrigation system options:

Each of these options has its own unique benefits and can be tailored to your specific needs and preferences.

The soil moisture sensor is a crucial component of our DIY plant watering system, and it's surprisingly easy to use. It works by acting as a variable resistor whose resistance varies according to the water content in the soil.

To connect the sensor, you'll need to attach it to your Arduino board. The sensor has four pins: DO (Digital Output), VCC, GND, and the module's power and ground connections to the probe. You'll use three of these pins in our project.

The DO pin gives a digital output of the internal comparator circuit, which you can connect to any digital pin on your Arduino. In our project, we'll be using digital pin 6.

The VCC pin supplies power to the sensor, and it's recommended to power it with between 3.3V and 5V. The GND pin is the ground connection.

By adjusting the built-in potentiometer, you can set a threshold for the digital output. This means that when the moisture level exceeds the threshold value, the module will output LOW, and the Status LED will light up.

To calibrate the sensor, insert the probe into the water when your plant is ready to be watered, and adjust the pot clockwise until the Status LED is ON. Then, adjust the pot back counterclockwise just until the LED goes OFF. That's it – your sensor is now calibrated and ready for use.

Here's a quick rundown of the sensor's connections:

I built a drip irrigation system to water my balcony vegetable garden with the right amount of water automatically.

The irrigation system is connected to my smart home and can be controlled remotely with the app on my phone.

To make the system work, I used a simple irrigation controller for a few years, but it was very limited in the scheduling of irrigation times.

The irrigation controller worked on batteries, which often needed to be replaced.

I decided to make a system to turn the water on and off with home automation to control the watering remotely.

With this system, I can choose how long to water every time I want to, which is very convenient.

I can also set times at which to water automatically, which is very important for my plants.

The system will be combined with soil moisture sensors in future guides to adjust the amount of water even better.

I can control the watering remotely from the app, for example when I am on vacation.
