Dew condensation on the leaf surface of greenhouse crops causes diseases by fungus, and thus badly affecting the growth of the crops. In this paper, we present a WSN based automatic control system to prevent dew condensation in the greenhouse environments. The system is composed of sensor nodes for collecting data, base nodes for processing collected data, relay nodes for adjusting the environment...
Farmland monitoring is of great significance in precision agriculture. In this paper, we design a wireless sensor network to monitor farmland information, including air temperature and humidity, light intensity, soil moisture, soil PH value, and the growth of crops. We carry out an experiment in the cornfield of Hongzehu farm. It shows that the monitoring system is effective.
Temperature and humidity are two important factors to the crops growth and product quality in greenhouse. A study on the space-time distribution of humiture in greenhouse is required. The green house humiture monitoring system based on ZigBee wireless sensor networks (ZWSN) is the best solution. The objectives of this study are: (1) to develop ZWSN nodes for measuring the temperature and humidity...
This paper presents the design and the implementation of a Wireless Sensor Network that can monitor the air temperature, humidity and ambient light intensity in a crop field. This can help the end users such as farmers in the better understanding of agriculture practices to be adopted for crop management. Since, early detection of plant fires is necessary to prevent high crop damages; a plant fire...
The wireless sensor network, which refers to the combination of sensors, embedded system, MEMS, distributed information processing and wireless communication network has become a hot topic in the research field because of its wide application prospect. This paper propose the design of an environmental monitoring system for valuable medicinal herb growing based on wireless sensor network, which gives...
