Introduction: An oxygen sensor‚ or lambda sensor‚ is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under supervision by Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The most common application is to measure the

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

interest in wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion‚ with the end goal of handing their processed data to a base station. Sensing‚ processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications [A1]‚ [A2]. Sensor networks provide

APPLICATION OF CHEMICAL SENSORS IN MECHANICAL ENGINEERING A chemical sensor is a device that transforms chemical information‚ ranging from the concentration of a specific sample component to total composition analysis‚ into an analytically useful signal. The chemical information‚ mentioned above‚ may originate from a chemical reaction of the analyte or from a physical property of the system investigated. Chemical sensors its application in various fields of engineering like civil‚ environment‚ medical

LINEAR POSITION MEASUREMENT USING A MAGNETORESISTIVE SENSOR Abstract: A smart transducer used to measure the linear displacement of an object in a magnetic field is presented. The application is to be safely used for demonstration purposes in the Playpen laboratory. The system uses an array of five HMC1501 Magnetoresistive (MR) sensors to sense the position of a magnet attached to the moving object. The system also has the ability to monitor the ambient operating temperature and detect if it is
