Abstract

Abstract: Aimed at the different demand for CO2 concentration of plants during the growth， a set of automatic CO2 control system was designed to offer the sustainable favorite growth conditions for crops cultivated in greenhouse. Based on the characteristics of greenhouses， the designed system adopted STM32 of Cortex\|M3 kernel as the core， and applied GPRS wireless communication technology to realize the automatic monitoring and controlling of CO2 concentration in greenhouses. The test results showed that the system was reliable and easy to use. Besides， this system possessed good scalability， and thus had good application prospects.
