A Review of Sensor Node in Wireless Sensor Networks

Wireless Sensor Networks WSNs are collection of tiny sensor nodes capable of sensing, processing and broadcasting data correlated to some occurrence in the network area. The sensor nodes have severe limitation, such as bandwidth, short communication range, limited CPU processing facility, memory and energy. Enhancing the lifetime of wireless sensors network and efficient utilizations of bandwidth are essential for the proliferation of wireless sensor network in different applications. We provide an in depth study of applying wireless sensor networks WSNs to real world habitat monitoring. A set of system design requirements were developed that cover the hardware design of the nodes, the sensor network software, protective enclosures, and system architecture to meet the requirements of biologists. Although researchers anticipate some challenges arising in real world deployments of WSNs, many problems can only be discovered through experience. We present a set of experiences from a four month long deployment on a remote island. We analyze the environmental and node health data to evaluate system performance. The close integration of WSNs with their environment provides environmental data at densities previously impossible. We show that the sensor data is also useful for predicting system operation and network failures. Based on over one million data readings, we analyze the node and network design and develop network reliability profiles and failure models.

Additive Manufacturing of Leaf Spring

Additive manufacturing AM , colloquially known as 3 D printing, refers to set of emerging technological that offer unique capabilities However, this design freedom is countered by build envelope and production rate constraints characteristic of most commercially available AM equipment. This paper presents an approach for architecting complex additively manufactured products using the design structure matrix DSM , a methodology that can map out components and interfaces at the system level. By building and manipulating a DSM of a proof of concept product, various architectures are explored considering size and structural constraints of additively manufactured components.

Development and Optimization of Process Parameters of Microwaved Cured Polymer Based Natural Fibre Coir Reinforced Composite

Now a days the processing of natural Fibre reinforced polymer composite through microwave curing going on a fortunate steps for better properties. It has been observed that the application of NFRPC is increasing day to day. Due to their low cost and light weight that type of composite is applying at various light load capacity areas. Processing of NFRPC depends on a large no factors. Due to practical constraint 3 domen parameters were considered during experimental investigation. The value of the parameter were selected on the basis of material characteristics and experimental available in the Laboratory. Design of Experiment were used for planning the experiments. Optimum process parameter were determined for improvement ultimate tensile strength. The selection of optimum parameter was assured by mechanical testing as well as microscopic structure. Processing of composite by using optimized parameters resulted in improvement in tensile strength by 3 . The ANOVA table was prepared and table was shown Curing Time is one of the main crucial parameter which affects the composite processing.

Performance of Ultrasonic Testing for Different Steel Sheets which are joined by Spot Welding

The main purpose of this paper is to examine the applicability of spot welded dissimilar steel sheets to ultrasonic testing, because resistance spot welding of the steel sheets is widely used in the car bodies and transport fields and ultrasonic testing is a good way to evaluate the fatigue life of the spot welds. Methodology of this paper is that two different steel sheets AISI 304 type austenitic stainless steel sheet and Galvanized steel sheet were welded to each other by using resistance spot welding. Some pre welding tests were made to obtain suitable and optimum weld nugget diameter and the welding current vs. nugget diameter curve were obtained. By using this curve and keeping constant welding parameters such as current, electrode pressure, weld time, etch. Fully identical four spot welded specimens having 5 mm ±0.16 nugget diameter were obtained. The specimens and nugget diameters were tested by using a special ultrasonic test apparatus which is designed for spot welded joints. Findings are that after the first ultrasonic tests, the four identical spot welded sheets which have AISI 304 "“ Galvanized steel sheet combination were subjected to the fatigue test in four different numbers of cycles. There is no any rupture or fracture in spot welded joints after fatigue tests. The spot welded specimens subjected to fatigue test were tested in ultrasonic test apparatus to observe the variation in the weld nugget and joint. The ultrasonic test results before fatigue and after fatigue were compared with each other and the decreasing of the weld nugget diameter were observed while increasing the number of cycles. The results were shown in figures and discussed. Spot welding of different steel sheets forms different microstructures which respond different values to ultrasonic testing. Evaluation of these responses are quiet difficult. Only a few spot welds can be evaluated among approximately 5 thousands of spot welds on a car body. Only selected spot welds can be ultrasonically tested. Resistance spot welding of AISI 304 and galvanized steel forms austenitic, martensitic and ferritic microstrucutre in the same weld region. Ultrasonic testing of austenitic microstructures is different than the other microstructures. In this study the response of different microstructures to ultrasonic waves are investigated.

WSN Based Temperature Monitoring System for Multiple Locations in Industry

Wireless sensor network technology has demonstrated a great potential for industrial, commercial, and consumer applications. Speci cally, in process monitoring and control, process data such as pressure, humidity, temperature, ow, level, viscosity, density and vibration intensity measurements can be collected through sensing units and transferred wirelessly to a control system for operation and management. Adopting WSNs for process monitoring and control provides great advantages over traditional wired system. In today's world we are facing with many di erent types of emergencies in the indoor environment. Response to such emergencies is critical in order to protect resources including human life and also we can save property from damage. This wireless sensor network for Temperature monitoring System which can report the emergency to the users in various forms, such as pop ups on a Computer screen, SMS on their cell phones and so on. Due to this exibility of reporting low cost wireless sensor network prepared for emergency response system of future. We are going to develop three wireless sensor nodes and we have to place in di erent position in the building using arduino board and we have to inform to the master node or monitoring node about the temperature available at each sensor node. While sending data to each and every sensor is very costly. Hence nodes are connected to WSN and their is only one node called 'Gateway' which collects the data from all other nodes and sends it to the cloud.

Dc House An Alternate Solution for Rural Electrification

In today's date, India is a large consumer of fossil fuel such as coal, crude oil etc. The rapid increase in use of Non renewable energies such as fossil fuel, oil, natural gas has created problems of demand and supply. Because of which, the future of Non renewable energies is becoming uncertain. Now a day's electricity is most needed facility for the human being. All the conventional energy resources are depleting day by day. So we have to shift from conventional to non conventional energy resources. In this the combination of two energy resources is takes place i.e. wind and solar energy. This process reviles the sustainable energy resources without damaging the nature. We can give uninterrupted power by using hybrid energy system. Basically this system involves the integration of two energy system that will give continuous power. Solar panels are used for converting solar energy and wind turbines are used for converting wind energy into electricity. This electrical power can utilize for various purpose. Generation of electricity will be takes place at affordable cost. This paper deals with the generation of electricity by using two sources combine which leads to generate electricity with affordable cost without damaging the nature balance.
