The information monitoring points for greenhouse environment were scattered, so a wireless sensor network with star-type network topology was designed and the wireless monitoring system for greenhouse was developed. By employing CC2430 chip as the core hardware, WSN implemented real-time data acquisition and remote wireless transmission. The field data was transmitted to the monitoring host through RS-232 interface. The node management software was developed based C language and the data management software was developed using LabVIEW 8.6. The system was featured by low cost and simply installation. The primary experiments show that the system performance is stable and can meet the design requirement of remote data acquisition.

Among the new trends in technology that have emerged through the Industry 4.0, Cyber Physical Systems (CPS) and Internet of Things (IoT) are crucial for the real-time data acquisition. This data acquisition, together with its transformation in valuable information, are indispensable for the development of real-time indicators. Moreover, real-time indicators provide companies with a competitive advantage over the competition since they enhance the calculus and speed up the decision-making and failure detection. Our research highlights the advantages of real-time data acquisition for supply chains, developing indicators that would be impossible to achieve with traditional systems, improving the accuracy of the existing ones and enhancing the real-time decision-making. Moreover, it brings out the importance of integrating technologies 4.0 in industry, in this case, CPS and IoT, and establishes the main points for a future research agenda of this topic.
