Hydroponic Control System Automation

Hydroponic Control System. Plants can be grown hydroponically without using soil. Instead, plant roots have immediate access to water sources that are nutrient-rich and provide all the nutrients necessary for growth and success.

Hydroponic Control System

It is a neat, orderly, and small environment for growing. These systems are frequently indoors, with precisely controlled microclimates enabling precise environmental conditions to ensure maximum plant growth with little exposure to risks like pests, frost, flooding, and similar phenomena.

This will make it possible for farmers to harvest a sizable amount of high-quality produce with almost no risk of loss from climatic or microbial contamination.

Where there is no room for conventional agriculture, crops can be grown in these vertical indoor farms. They can also grow all year long, no matter the climate or the weather.

Many people have high hopes that hydroponic farms will end food deserts and supply underserved communities with healthy, fresh produce.

When carried out properly, hydroponics is also a highly sustainable method. By repeatedly cycling water through the system, it uses much less water than conventional agriculture. Additionally, it doesn’t contribute to soil degradation, a major issue in the modern world.

As a result, a large number of amateur and professional growers have entered the hydroponics industry.

Benefits of Hydroponics

  1. Less resources are needed, including less land (about 240 times as productive as conventional farming), water, and energy ( In case Greenhouse)
  2. High Quality Produce because the environment is strictly controlled.
  3. Sustainable farming while water is being recycled and treated.
  4. Seasonally pessimistic.

Shortfalls

  • Commercial installation: Expensive initial setup
  • Setup for businesses: When growing indoors with temperature control and indoor lights, there is a high energy consumption.

With the right automation in place, having a hydroponic setup at home as a hobby grower has almost no drawbacks because it is self-sustaining. It is simple to set up and takes up little room.

This device, which is based on the Raspberry Pi Zero W, was created to automate repetitive tasks and remove uncertainty for growers. In order to reduce daily tasks and make the setup self-sustaining, sensors were needed. It is designed to create the favorable, dependable conditions needed for plants to grow healthily. It is entirely powered by Node (JS).

To find out the status of the produce and whether there are any pests or diseases affecting the plants, one can access live feed from the farm.

For plants to remain healthy throughout every stage of growth, it is essential to maintain the proper nutrition level of water. pH and electrical conductivity sensors are used to determine the nutritional value of the water.

When the right humidity and temperature conditions are kept, plants flourish.

  • Ambient humidity and temperature
  • Nutritional pH level in parts per million (ppm)

— Controls

Pumps and LED lights are electronically switched in accordance with predetermined schedules. This guarantees the necessary repeatable and reliable environment.

Schedule for LED Lights (UV grow lights) (Typically one shift of 12 hours)
Pump Doser Nutrition Schedule

  1. 5MP 4 Channel Open Contact Relay (230V / 10A per channel rated) camera
  2. pH sensor (Resolution: 0.15PH (STP); Range: 0–14PH)
  3. EC Sensor (Resolution: 5% (STP), Range: 0-2000us/cm)
  4. Temperature Sensor (Resolution: 0.1 °C, Range: -40 to 80 °C)
  5. Humidity Sensor (Resolution: 0.1%RH, Range: 0-99.9%RH)
  6. 12V/2ADC through a wall adapter is the power source.
  7. Dimensions: Wall mount, 90 x 134 x 36 mm (W x L x D).

The benefit of hydroponics is that most parameters can be closely monitored and controlled, leading to repeatable results.

Grow lamps

To speed up plant growth, grow lights’ wavelength and intensity must be maintained. The light spectrum is measured and adjusted to set this. The 14 hours of ON time and 10 hours of OFF time for the lights are scheduled.

Pump, Water

Plants use water to take up nutrients and oxygen as they grow. Therefore, it’s crucial to keep the water in the tank moving. Additionally, stagnant water serves as a haven for bacteria and mosquito larvae. The water pump is set to run every 30 minutes.

Nutrition

The system takes a sample from the tank at predetermined intervals to guarantee that the proper pH and ppm level are maintained. If the pH or ppm are below or above the necessary level, appropriate action is taken before repeating the measurement.

Temperature

It is kept at the appropriate ambient temperature and humidity for the plant. The PID algorithm is used to maintain the humidity and temperature.

FAQ Hydroponic Control System

How do you automate a hydroponic system?

Jalkrishi – Automated Hydroponic System from C-DAC The solution is pumped into the gutter where the plants are grown with suitable support cups. Plant roots directly absorb water and minerals. The overflow solution is collected in the recycling tank and pumped back to the mixing tank for reuse.

How to control the water level in hydroponics?

Mention 3 disadvantages of hydroponic system?

5 Disadvantages of Hydroponics Expensive to set up. Compared to traditional gardens, hydroponic systems are more expensive to acquire and build. Vulnerable to power outages. Requires constant monitoring and maintenance. Waterborne diseases. Problems affect plants more quickly.

What is the most efficient hydroponic system?

Aeroponics systems have a number of advantages over traditional hydroponics. This system uses 95% less water than traditional planting, and 20% less water than other hydroponic systems. The fine mist of the aeroponic system allows laser accuracy of nutrition application.

What is a smart hydroponic system?

With this model, plants grow without soil and use nutrient solutions in water. When farmers apply smart hydroponic systems, crops grow quickly with uniform product quality and yields 30 to 40% higher than conventional cultivation.

How to grow plants hydroponically yourself?

To grow hydroponically, you need plants, a container, water, a way to anchor the plants, nutrients, and a light source. It is possible to grow vegetables hydroponically both outdoors and indoors. If grown indoors, artificial lighting will help it grow faster.

How long should water flow in a hydroponic system?

You don’t want to let the roots soak for too long or you run the risk of drowning them. Here’s what we recommend: water long enough to completely flood your tray and then let the system drain. Most timers are set to increments of 15 minutes or less.

Is tap water OK for hydroponics?

To answer the question – can you use tap water for hydroponics? The answer is yes. Get to know the water in your area. Know your water’s chlorine, chloramine and PPM levels and treat them properly before starting.

Do I need to change the water in my hydroponic system?

Full Water Replacement The best time to completely replace your hydroponic water is after you have filled it long enough to fully fill it. For an average-sized hydroponic system, you may need to change the water every two to three weeks.

Why is hydroponics not popular?

5 reasons why hydroponics is not popular are: 1) lack of organic certification; 2) hydroponic complexity; 3) high initial costs; 4) lack of awareness and accessible technical knowledge; and 5) higher maintenance and continuous observation.

Is hydroponics healthy?

A hydroponic system gives you complete control over the nutrients your plants receive. But are hydroponic nutrients safe for the environment and the plants themselves? The simple answer is yes…as long as you use the right nutrients and understand how to dispose of them properly.

What pH should be maintained in hydroponics?

between 6 to 6.5 The nutrient solution used for soilless cultivation should have a pH between 5 to 6 (usually 5.5), so that the pH in the root environment is maintained between 6 to 6.5. This is the pH range in which nutrients are most readily available to plants.

What is the best hydroponic system for beginners?

What is the best hydroponic system for beginners? Deep Water Culture (DWC) is the easiest type of hydroponic system you can build and maintain at home. In this system, plants grow with their roots submerged directly in nutrient-rich water.

What type of hydroponics is best?

Hydroponics Drip System Both cost effective and easy to manage, it’s hard to go wrong. The premise of a drip system is to allow nutrient-laden water to flow by gravity (dripping) downwards through the plant’s root system.

How often do you change the water in the DWC system?

As a general rule, you should completely change your reservoir at least once every two weeks in the vegetative stage, and at least once a week in the flowering stage.
