In order to satisfy the requirement of greenhouse crop to be produced at high quality and high yield, the existing GSM network can be used for implementation of the system, this paper introduces a inquire and control system aims at greenhouse information through sending SMS,based on GSM communication module TC35 and STC11F32XE microcontroller . Its peripheral circuits also include five sensor modules, driver circuit module, key input module, power management module, LCD module.It aims to measure and record the temperature and humidity of the atmosphere, illuminance, carbon dioxide density and the temperature of the soil in the greenhouse.Besides that,it can be requested the information of the sensors and be controlled by SMS, this system will alarm locally and send an alarmed message to you when greenhouse environmental indicators overruns. The paper focuses on data acquisition and data transmission by GSM. We have made a prototype and a test ,through the test and operation,the system transmit data fast and accurately, important indicators of greenhouse can be adjusted fast and sensitively. It provides a method for the efficient control of greenhouse environment.
