ABSTRACT
A sensor is a miniature component which measure physical parameters from the environment. Sensors measure the physical
parameters and transmit them either by wired or wireless medium. In wireless medium the sensor and its associated
components are called as node. A node is self-possessed by a processor, local memory, sensors, radio, battery and a base
station responsible for receiving and processing data collected by the nodes. They carry out joint activities due to limited
resources such as battery, processor and memory. Nowadays, the applications of these networks are numerous, varied and the
applications in agriculture are still budding. One interesting application is in environmental monitoring and greenhouse
control, where the crop conditions such as climate and soil do not depend on natural agents. To control and monitor the
environmental factors, sensors and actuators are necessary. Under these circumstances, these devices must be used to make a
distributed measure, spreading sensors all over the greenhouse using distributed clustering. This paper reveals an idea of
environmental monitoring and greenhouse control using a sensor network. The hardware implementation shows periodic
monitoring and control of greenhouse gases in an enhanced manner. Future work is concentrated in application of the same
mechanism using wireless sensor network.
