ABSTRACT
The greenhouse environment monitoring and control obtains the optimal growth conditions for crops through changing the greenhouse environment factors (such as temperature, humidity, light intensity, etc.) (Zhang, 2013; Guo, 2010; Chen, 2011; Mittal, 2012), so as to prevent crop disease, improve crop quality and increase economic benefits. Our country is a large agricultural country with vast area, and every year serious losses are often caused by natural disasters to crops (Robert, 2008; Zhang, 2013; Zhao, 2012). Deploying the sensor nodes within the farm, access to climate conditions in real time and make corresponding measures are helpful for improving the yield of plants. Many scholars have conducted the research
and avoid the influence of climatic conditions on crops (Liu, 2015; Li, 2009). Greenhouse also plays an important role in anti-season vegetables and flowers. Traditional greenhouse monitoring system is mostly implemented by the wired multipoint system with complex wiring, difficult installation and poor anti-interference ability. The wireless transmission can solve the shortage of the traditional greenhouse monitoring, but Bluetooth and Wi-Fi can only achieve the short transmission control. GSM and GPRS can realize the wireless transmission control, but the SMS cost and traffic cost are high.
