communication‚ a reality. Such nodes are called as sensor nodes. Each sensor node is capable of only a limited amount of processing. But when coordinated with the information from a large number of other nodes‚ they have the ability to measure a given physical environment in great detail. Thus‚ a sensor network can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional networks‚ sensor networks depend on dense deployment and co-ordination

IEEE SENSORS JOURNAL‚ VOL. 6‚ NO. 3‚ JUNE 2006 631 Magnetic Sensors and Their Applications James Lenz and Alan S. Edelstein Abstract—Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include

WIRELESS SENSOR NETWORK (Reshma Bhat‚ 3rd sem‚EC) Abstract A Wireless Sensor network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions‚ such as temperature‚ sound‚ vibration‚ pressure‚ motion or pollutants. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance and are now used in many industrial and civilian application areas‚ including industrial

Describing Sensor Performance: When describing sensors and instrumentation systems we make use of a range of terms to quantify their characteristics and performance. It is important to have a clear understanding of this terminology‚ so we will look briefly at some of the more important terms. • Range: This defines the maximum and minimum values of the quantity that the sensor or instrument is designed to measure. • Resolution or discrimination: This is the smallest discernible change
