GSM Based Greenhouse Environment Monitoring System

Abstract

Greenhouse monitoring is a needed one for variable climate changes. GSM technologies have been rapidly improving wireless technology during few years. Initiating from industrial controls and telecommunication, it is now being applied in environmental monitoring and agriculture. The existing system has the ability to yet lack the ability to control indoor humidity and other parameter. This paper propose modern greenhouse measurement system, the GSM-SMS and sensors are used to sense necessary green house parameters and transmit data using wireless communication. This project is used to measure the various parameters like Temperature, Gas and light. Values of these sensors are displayed on a LCD. These parameters are sensed by sensors and sensor output is amplified and given to ADC. ARM processor controls these parameters and keeps them at some predefined values using relay interface. At the same time these current values of all parameters are sent through SMS using a GSM modem.
