Story

we are having a very good project for you. this is known as the automatic plant watering system. In this project, we are nurturing the plants using technology. we did it for a month and notice that the plants have better growth.

So, here we are going to share our full research and how we made it, and what was the result. so, if you want to make this smart irrigation using the Arduino system on your own just read and follow our article. we will share all the information from construction to code. so, without any delay let’s get started.

Here are some plants with us all the pots have some sensors and a water dripping system. which will monitor the water into the soil and maintain the required amount of water in the pot. if the plant required the water in this smart irrigation system then the water pump starts and watering the plant with accuracy and when the plant got the required amount of water then the water pump will shut down.

according to their water requirement.

An automatic watering system for plants. soil moisture sensor which can sense the moisture in the soil. The soil moisture sensor is associated with the relay which will be triggered to start the water pump.

another plant we have taken is sadabahar(periwinkle) plant it required daily water. and the last one is the cordyline plant which is in the middle of both plants which we have taken.

we are using a source of water in which the water pump lye down. we are also making and water level detector for this reservoir. how much water remains in the tank we will get to know by the display we are using

Now we are calibrating all the sensors as per the requirement and there are different threshold values for each plant sensor. Each sensor gives the difference value according to the soil condition. All the things like soil condition for all sensors and water level of resource water will be displayed over the 16X2 display.
