Wireless sensor networks include many different distributed wireless sensor nodes that are capable to sense noise, vibration and temperature. All the nodes have own battery, memory, a sensor and a processor and are autonomous as well. These nodes are heterogeneous, reliable, fault tolerant, scalable and they need low power consumption. Today, the sensor networks are being employed everywhere such as in traffic controlling systems, in green houses, in forests to find fire, in military to examine spy activities, in homes to check water and waste water and in many other places. Thus, wireless sensor networks have become a very important technology to live with.
These networks are used in greenhouse monitoring where the plants are grown. To establish wireless sensor networks in a greenhouse the nodes are put on crops and leaves. The fundamental node is responsible for gathering information from all nodes and communicating with the main server or computer. Wireless networks for greenhouse monitoring is necessary for the owner of the greenhouse who wants optimum cultivation of crops in any environmental situations. The nodes of these networks senses temperature, light, carbon dioxide level, humidity, radiation etc. Examining these environmental elements consistently helps collect data about the plants and crops in the greenhouse.
Data collected is then manipulated to deal productivity of crops. At whatever time there is a modification such as sudden increase or decrease of temperature, the manager will be informed about the situation of struck region through SMS, or email or call or any other way like doorbell by the information communication system. Then the manager takes suitable actions. Wireless sensor network nodes communicate with each other and share essential and significant information that will be useful for network. The topology of network is employed for such networks that depend on complete area of the greenhouse, cost and other elements.
Information stored through sensor nodes on the PC is then manipulated and significant interpretation is gained through data mining and knowledge management techniques. It offers installment flexibility for sensors, faster deployment and better sturdiness than wired networks. Basically, wireless networks are measurement tools that are applied in greenhouse areas to measure and maintain growth of crops. This saves cost and energy of wiring and linking all nodes. It only charges to establish and maintain the network. These networks are very convenient to manage greenhouse in real time in more efficient manner. It is also better to use such technology rather than wasting money in inferior evaluations and labor that is standard faced during crop cultivation.
There are lots of manufacturers making different types of sensor networks with wireless benefits to choose from. Since there are lots of names to choose from, you will find it very much hard to choose the most reliable and reasonable name from the bunch. Before choosing a company or service provider, you should check certain factors and confirm the reliability and functionality of sensor networks that you are going to use. Use wireless sensor networks for facilitating effective monitoring in your greenhouse ambiance.
