As the field of communication networks continues to evolve, a very interesting and challenging area of Wireless Sensor Networks (WSN) is rapidly coming of age. Wireless sensor networks are an attractive means to monitor environmental conditions and to bridge the gap between the physical and the digital world. Wireless Sensor Networks are highly distributed networks of small, wireless nodes deployed in large numbers to monitor the environment or a system. The nodes cooperate and collaborate on their data, which leads to accurate sensing of events in the environment. The gateway node interfaces sensor network to the external world through internet network / 3G.<
Wireless Sensor Network (WSN) Technology has been listed as one of the emerging and enabling technology with the potential to revolutionize Information and Communication Technology. Applications of WSN extend to vast and diverse areas such as the Industrial Monitoring, Building Automation, Environmental Monitoring, Disaster Response, and Precision Agriculture etc. <

3.0 Application Areas:
Using Ubimote and wireless sensor networks it is possible to manage crop cultivation and to know the exact condition in which plants are growing from the comfort of your own home. By combining sensors such as humidity, temperature, and light, the risk of frost can be detected, possible plant diseases or watering requirements based on soil humidity, among others. This helps to control conditions in nurseries and to closely monitor high performance or delicate crops, such as vines or tropical fruit, where the slightest change in climate can affect the final outcome. All of this information can also help us to determine the optimum conditions for each crop, by comparing the figures obtained during the best harvests. Given their ease of use and scalability, wireless sensor networks can also be used to monitor isolated areas of difficult access. Ubimote detects environmental values and can store them temporarily, send them to a data processing centre for analysis or send emergency alarms. For example, depending on soil humidity it will send a message (through the ZigBee network) to stop watering, thus contributing towards efficient water management.
Installing a wireless sensor network near animals or poultry can help optimize their rearing conditions. It is possible to monitor the temperature of litters to keep it at suitable levels or even to control animals stress levels by monitoring flock restlessness with vibration and movement sensors.
Protected Natural Environments
Through a wireless sensor network deployed using Ubimote it is possible to detect and prevent forest fires. To achieve this, it is possible to use infrared or smoke sensors to detect flames, heat and gases.After installing the WSN, the network can also acquire the daily values for temperature and relative humidity in order to determine the likelihood of a fire in each zone under surveillance. After analyzing this data it is possible to send an alarm to a mobile indicating the probability level and the area, helping to focus the efforts of reserve forces more productively.
Data Centre environment monitoring system
DCEMS is a temperature and relative humidity monitoring system which runs on Zigbee protocol, collects temperature and relative humidity data from various places using Ubimotes. DCEMS graphical user interface displays a circle for each node in the network and shows their respective 16 bit network addresses and data that it sends inside that Circle. Currently DCEMS GUI supports up to sixteen nodes, means it can display up to sixteen circles to represent 16 Ubimotes in the network.
- Collects data from Ubimotes from different places and displays whole data at one place.
- Provision to give alternate name for each of the node in the network instead of network addresses being displayed.
- Creates log files for each of the nodes with timestamp, temperature data, humidity data, node address and user provided alternate name.
- Provision to set threshold temperature and humidity value.
- Sends SMS alerts with user provided alternate name and temperature value when temperature value of a particular node exceeds threshold value.
- When a node is out of network or removed from the network, GUI removes corresponding circle form the display. When the same node is rejoined, GUI adds corresponding circle to the display automatically with 16 bit address and data.
- Intensifies the circle color to represent data updates form the nodes in the network.
- Shows SMS alerts status in the web browser.
