HYDROSOL

Inspiration- Hydroponic is basically the method of growing plants without soil. It only grows with help of water. This type of farming is much popular in the areas where the quality of soil is not good and unsuitable for agriculture. Green Veggies like Lettuce, Spinach and Herbs like Tulsi, Mints and Tomatoes, Cucumbers and Beans can be grown in Hydroponic Farming. This type of farming can happen at both small scale and large scale. Now, this type of farming majorly requires 3 factors- Water, Favourable Temperature, Nutrients. Now, if we don't take care of these 3 factors, how will we grow the plant? So, we need to attend plants for a long time. But we all have a busy life, how will we attend the plants. Then came the idea of HYDROSOL.

What it does -

1. It can do real-time checking of water level in the Hydroponic plant tray.
2. It can accurately check the temperature, humidity, water quality and many other things.
3. This setup would become a one time investment as you don’t need to worry about the plants as they are in the safe hands of automation.
4. This project will work with the help of solar energy.

How I built it- First, I designed and 3D printed a tray that could fit into a rectangular container and made an opening for water level sensor, which helped in sensing the water level in the container. Then, I connected it to my Arduino which was pre-programmed. Then, I checked it was working and it was also giving the correct output. Then, I connected it to DHT-11 Sensor which is used for checking temperature and humidity. I made a stand near the tray which held the DHT-11 upright and connected it to the Arduino. Then, the TDS sensor was also put in the tray to check the pH level of Water because Hydroponic farm requires clean water and neutralized water. I also put a small chlorine tank which cleaned the water if there was any change in the pH level and also kill the germs. There is also an Optical Transducer which checks the quantity of nutrients in the soil/water. Then I had added a small solar panel with a solar module which powered the Arduino

Challenges I ran into- Main problems were lack of research and time and no availability of components in the market.

Accomplishments that I'm proud of- I did a good amount of research in short time and also completed the project.

What I learned- I learnt many things from the research and also learnt many programs of Arduino and also about sensors.

What's next for HYDROSOL - Make sure it works with IOT and Home automation.
