A self-adaptive greenhouse CO2 concentration monitoring system based on ZigBee

CO2 is one of the main raw materials, which is used for plant photosynthesis and synthetic organics. Because the content of CO2 affects crop yield and quality directly, this paper designs the monitoring and controlling system of greenhouse CO2´s concentration based on ZigBee wireless network. This system, taking the microprocessor CC2530 as core, is mainly made up of data acquisition module, control module, executive module, power supply module and user interactive module. The real-time monitoring on the greenhouse concentration of CO2 is completed by each module´s coordination work. This system uses ZigBee wireless network system to achieve data collection.
