IMPROVED REMOTE-CONTROL WIRELESS SENSING SYSTEM OF PLANT GROWTH FACTORS IN GREENHOUSE ENVIRONMENT

Plant growth factors including carbon dioxide, temperature, humidity and luminance have been detected by using the proposed remote-control wireless sensing system in greenhouse environment. These factors are crucial for photosynthesis and can be detected in real-time by this system. Numerical sensors were adopted and were driven by the developed printed circuit boards. Remote-control and wireless data transmission were also performed and improved by using the developed hardware. In order to satisfy the requirement of remote control, GSM module was integrated in the sensing system. Meanwhile, corresponding software was developed for data storing, wireless transmitting, remote controlling and data analyzing. The proposed system is suitable for precision management of key factors in greenhouse and it also exhibits improved functional performance compared with our previously reported sensing system.
