A Smartphone Controlled Fertilizing and Plant Watering Garduino

We know that plants require water for their survival, but all of them don't need the same amount of water. Too much or too little water both can be harmful to the plants. In the same way, fertilizing the plants are also important as most of the soils are infertile these days. The objective of this paper is to develop a robot that can tell us how much water a plant requires and water it accordingly as well as fertilize it. This robot is being controlled by a Bluetooth module, and it carries a water and fertilizer tank, a soil sensor, and a digital display. Initially, the soil is fertilized, then the soil sensor is implanted into the soil, and the moisture percentage is displayed in the digital display, accordingly, the plants are watered until the moisture content reaches 100%. This system helps in watering and fertilizing the plants properly so that the plants can thrive.
