IoT Plant Watering and Fertilizing System

Abstract

Internet of Things or IoT is an advance technology that allows user to control hardware devices through the internet. In this work, IoT technology is used to water and fertilizing the plants when needed. This system is created to make user’s daily life easier than before since the process of watering and fertilizing the plants can be done by using user’s mobile phone.  Moisture sensor is placed at soil to give input to Arduino UNO microcontroller. Then, a user will be notified the condition of the soil moisture through Blynk application at their mobile phone. The water pump then receive an instruction from microcontroller to water the plants with the correct amount of water until the soil dryness reading is change from ‘High’ to ‘Low’. This situation indicate that the plants is receiving enough water from the soil. Besides, fertilizing system will be activated once the time duration is triggered. User can set the time duration at any time they want to do fertilizing. In a nutshell, this project not only can save a lot of user’s energy, the time and money can be affected too since we already have an automatic system that can replace the traditional system.
