ARDUINO based Approach to Provide Optimum Conditions for Indoor Cultivation

Abstract

This work describes a framework to provide an optimum environment for indoor cultivation. The optimum conditions like temperature, soil moisture and solar radiation can be controlled by using an ARDUINO microcontroller. The system is basically aclosed loop system where the gathered data from the sensors (say measure data) will be compared with the user data(which is set by user and can be incremented or decremented through switches). If both the data i.e., user data and measured data are same, then the controllers will not execute. The controllers will execute the control action only if the user data and measured data have different readings so that these controllers can adjust for optimum environment (temperature, soil moisture and solar radiation). An LCD is provided to display both the readings. The indoor cultivation system consists of both hardware and software. Hardware includes microcontroller, temperature sensor(LM35), soil moisture sensor, an LDR sensor, anLCD, a relay, a halogen light, a water pump, solar radiation controller,a fan and switches. Software includes ARDUINO IDE.
