Abstracts: Many research and projects have been done in order to improve the condition and cultivation of crops under greenhouse. We would not be able to grow necessary cereals and pulses in future because of civilization is increase day by day so that the wide area of fertilize soil are covered by big buildings. Due to global warming the climate parameters are change instantly hence affect the crop and decrease the quality and profit of the farming system. We need a new and effective technology which can improve continuously the productivity, profitability, sustainability of our major farming systems. The purpose of this project is to develop control system for environment parameter in the green house using microcontroller. To evaluate performance of the developed system on the water requirement, temperature and humidity control in the greenhouse. Plants were grown in an automatic control system green house with mechanically ventilated and cooling system which provides control of relative humidity and temperature. The set points are saved in the EEPROM of the micro-controller. The data from temperature and humidity sensor were sent o AVR controller as digital input signal. According to the condition of set point it will actuate the output device.
