Greenhouse Environment Monitoring System using Near Field Communication ( NFC ) Technology
semanticscholar(2016)
Abstract
The best growth environment of greenhouse crops needs to obtain the information such as temperature, humidity and carbon dioxide concentration. In Near Field Communication, NFC, technology, the Arduino control module and the sensor are combined to develop a set of greenhouse environment monitoring system. The greenhouse environment monitoring system adopts modular solution. It includes Arduino control module, NFC R/W module, NFC tag, sensor, DS1302 clock module, SIM900A GSM module, etc.. The sensor collects greenhouse environment data, and the data is converted to digital form. NFC R/W module writes the binary format of the data in NFC tags word for word, and through the verification of data, ensures the validity of the data transmission. Software section divides the NFC tags into sectors and blocks through the Arduino language programming, and writes the corresponding data in the hour sector, minute sector, temperature sector, humidity sector and carbon dioxide concentration sector. Through the program, the interval time and total time of writing data are set respectively. when reach the total time, the system sends text messages to remind users to read the data, and imports the data into the computer database for further analysis. The data of NFC tags is finally reset. The experiment shows that the monitoring system can meet the needs of greenhouse environment control with the characteristics of stability and authenticity.
