This paper presents a design and working of system that can gather the data identified with greenhouse environment and control the system automatically with respect to the pre-defined ideal conditions. Different sensor and actuators are discussed below. Basic parameters like temperature, humidity and light is controlled automatically through micro-controller. Some of the time based functions are actuated by a timer. Irrespective of automatic control, all the pumps, fans and motors are manually controlled with the help of GSM (Global System for Mobile Communication). Necessary information is shared with the proprietor using GSM. The LCD (Liquid Crystal Display) is implemented at the greenhouse to display some of the parameters for observation and analysis.
