To solve problems that existed in wired water monitoring system, such as high cost and restricted monitoring water range, a kind of Lijiang River water environment monitoring system is designed based on WSN. In order to ensure long survival time of the sensor node and a high performance of routing node, MSP430 and ARM32F107 processor are employed respectively. After preprocessing data, MU709 3G module...
Wireless sensors network (WSN) is changing the interactive modes between human-beings and the natural world. ZigBee technology, as a newly-developed technology, has the advantages of low power consumption and latency. Combined with internet, ZigBee provides a new way to monitor biological information that is closely related to people's lives. In this paper, we build a biological information monitoring...
The temperature and moisture of single soil layer is difficult to represent the real growth environment around crop root. The measurement of temperature and moisture in multilayer and multipoint soil is easy to know water demand around crop root during its growth period deeply and accurately. It also can improve the water utilization coefficient and achieve basic data for the research on soil water...
A volcano monitoring system plays a key role for launching emergency early warning, and the use of alternative technologies have proven their effectiveness in this setting, which is the case of wireless sensor networks. For surveillance systems, the real-time requirement is mandatory due to the need for immediate access to the signals derived from a natural disaster where the goal is safeguarding...
This paper presents the development of prototype system for monitoring and computing greenhouse gases (GHG) with Unmanned Aerial Vehicle (UAV) deployment for collecting data for different nodes. This system is based on wireless ZigBee technology that transfers the data wirelessly to UAV, which function is as a router, from which data is sent again to a data logger. An ATMEGA328P microcontroller is...
How to protect the fresh water sources is one of the principal problems in the human society, and obviously the industrial sewerage is the main pollution source. However, some water quality monitoring systems based on WSN have been done; we found that the traditional WSN nods have a disadvantage of short-distance communication among the nods, which limits the application in monitoring the industrial...
Wireless sensor network (WSN) is a new technology that can provide processed real-time field data from sensors physically distributed in the field. Based on investigation and applications in precision agriculture, a wireless agricultural and environmental sensing system for crop monitoring is presented in the paper. The setup of smart crop monitoring system is based on TinyOS while system test is...
To meet the special requirements on micro-climate raised by the greenhouse in Northeast China, we develop a WSN-based greenhouse environment monitoring system. We decrease the power consumption of nodes, reduce the complexity of system development and simplify the deployment of nodes by dormancy mechanism, single-hop transmission, and on-demand deployment. Gateway node transmits the sensor data to...
In this paper a monitoring system for production well based on WSN is designed, where the sensors can be used as the downhole permanent sensor to measure temperature and pressure analog signals. The analog signals are modulated digital signals by data acquisition system. The digital signals are transmitted to database server of monitoring center. Meanwhile the data can be browsed on internet or by...
There are a number of major hazard installations in industry, which are the source of grave accidents, so it is urgent to take effective measures to control and manage these installations. In this paper, wireless sensor networks are introduced into the major hazard installations monitoring to develop a distributed real-time monitoring system for the first time. This system fixes up disadvantages of...
