    Green house effect
    (University of Management and Technology, 2011) Ali Nawaz; Ali Mehmood Malhi
    This is an automatated green house that is totally self operative unlike the traditional green houses. The idea of this autonomous green house is to provide such feasible conditions for a better growth of plant as are scientifically proved for optimum results. Autonomous green house includes an automatic temperature controlled system to control temperature to desired set point. The self cleaning feature will clean the green house from inside (i.e. water vapors, dust particles on the glass).Cleaning improves efficiency and provides maximum energy utilization. The automated sprinkling of water is yet another very salient features of this a state-of - the art green house. This system is pre programmed for water showering, as per the plant requirements minimizing the usage of human resources. In this project we are designing aqua flora caring green house. In this system we have controlled the temperature in the green house using LM35 temperature sensor, fans and heater. Which will be multiplexed using a multiplexer and will be convert to digital form using ADC.the working of the whole system will be controlled by 89s52 microcontroller. The light in the green house will be controlled by the placement of light sensors and a plane of light. Automatic watering and automatic cleaning will be done using motors which are operated by 12V relays which in turn are controlled by diode clump and microcontroller. For the display and input of temperature, light, automatic watering, automatic cleaning, and to set the desired value of temperature key pad and a 4*16 LCD will be used
