It is difficult to manually assess the amount of moisture required in the soil for the healthy growth of plants therefore the soil is either left dry for a long period of time, or flooded unnecessarily hence both destroy the nutrients and minerals from the soil that are vital for the plants. In this paper app based garden bot is developed for the automatic regulation of water level in plants. The system uses Raspberry Pi board as a base and low cost capacitive sensors for providing the low power consumption and cost effective solution to automatic irrigation of plants. The system is programmed using Python and Java based App where the communication between them is carried out based on the concept of socket forwarding. Key Words: Agriculture,Sensor, Irrigation system,Garden Bot,Android Application. 1. INTRODUCTION The optimal quantity of water is vital to the growth of plants where the level of moisture in the soil is one of the factors responsible for the healthy growth of plants. Due to limited water resources and water scarcity it is important to make efficient use of water resources for the quality growth of plants. The objective of irrigation system is to provide the adequate supply of water to plants. The manual irrigation system is not sufficient for efficient use of water resources. In accordance to the shortage of water and fluctuating weather conditions, the automated Irrigation system is crucial when the plants can’t be automatically watered when the people are away from their homes and irregular watering leads to mineral loss in the soil and end up the rotting of plants. Thus the automated irrigation system provides solution to the problem of watering from remote location, adequately sensing the soil moisture for the adequate supply of water to plants for their healthy growth. The android based garden bot using raspberry pie and capacitive sensors provides a low cost and power consumption solution for automatic irrigation system. The proposed automated irrigation system works on self made capacitive sensors and a Raspberry pi board (ensuring minimal cost and power consumption) for automatic irrigation using an android app based on sensor input and microcontroller. In this paper a design is proposed for automated irrigation system using Raspberry microcontroller and low cost capacitive sensors. A capacitive sensor is used to measure soil moisture and is inserted at various positions near to the plants. The sensor output is given to raspberry microcontroller. The level of water sensed by sensors is used as input to decide the manual/automatic on or off of motor controlling the supply of water to plants. Thus the automatic irrigation system has shown to be valuable in optimizing the use of water efficiently based on direct soil water measurements. 2.
