Sensors

manage the placement of wired and wireless sensors and sensor networks across large, and often remote geographic regions, as wells developing GIS interfaces to dynamically discover, query and task sensors within a service-oriented architecture (SOA) [2,3]. There are two types of sensing equipment (devices), which are stand alone sensors and sensors within network. Sensor network composed of node of the more sensing devices on the node stand alone sensors perform functions autonomously and don not

“What do you mean it won’t work with these sensors? They just bought a $1 Million dollar lighting system and the sensors for the animals were the most important part!” I found myself in a real dilemma. The project had to meet its deadline. Animals had been living in a temporary laboratory and needed to move into their permanent home and the last item on my deliverables was to setup the light sensors in the vivarium. I began gathering data, taking readings, pulling logs, verifying the rest of the

The GSM / GPS Module communication and the distance Sensor, checking the car’s distance from the surrounding cards so that the relay will be ON and turn off the engine. The goal to provide minimum 12 feet between the stolen car and the behind car The Choosing of the GSM/GPS to communicate with the Owner will provide a cheap, effective way to allow the owner to communicate with the stolen car. Also choosing the ultrasound distance sensor to provide the safe distance for the car to stop. Different

Effects of Protein Adsorption and Thrombus Formation on The Accuracy and Function of pH Sensors. Introduction: PH sensors are used in many scientific laboratories to measure the hydrogen-ion concentration of a liquid substance and to determine the basicity and acidity of a liquid. PH meters measure the electrical potential difference between a reference electrode probe and a pH electrode probe. Since these probes are very sensitive, they are required to be kept cleansed from contaminants. If exposed

A Simple, Fast and Memory Efficient Algorithm for Secure Communications in Wireless Sensor Networks Anusha Peddigari, Archana Tandra and L.K. Suresh Kumar Department of Computer Science and Engineering, University College of Engineering, Osmania University, Hyderabad. Email: suresh.lokhande, anushapeddigari94, archanatandra95 {@gmail.com} Abstract— Wireless Sensor Networks (WSN) introduce a new way to interact with the physical environment. The security in WSNs became an attractive area of

Momcilo V. Krunic, Miroslav V. Popovic, Vlado M. Krunic, Nenad B. Cetic [4] Energy consumption, indeed, represents one of the essential properties of embedded applications, mainly for those devices whose autonomy depends on battery life. The lack of precise and suitable methodology for energy consumption estimation for embedded applications based on ultra-low power heterogeneous multicore DSP platforms inspired a solution that will be presented by author in this paper. Author developed a plugin

framework involving theoretic teaching and scientific research. As early as in my junior year, I was guided by Professor Jia Huang in Tongji University to conduct an innovative research project "Organic Field-Effect Transistor (FET) based Humidity Sensor", in which FET was prepared from an organic semiconductor material and its moisture electrical inductive was measured. This project triggered my research interest in this field and prepared me well for later research challenges. I was excited to conduct

Link Quality Based Hierarchical Routing Algorithm for 6LoWPAN INTRODUCTION Wireless sensor network (WSN) is one of the fastest growing areas in networking world today. In order to convert WSN from personal area network (PAN) into low power personal area network (LoWPAN), IEEE standard 802.15.4 was introduced. However, future WSNs would consist of thousands of nodes and these networks may be connected to others via the internet. Hence, IPv6 over LoWPAN (6LoWPAN) is defined by Internet Engineering

Overall System A- Hardware Subsystem This system uses three components for map building Ultrasonic range sensor, Stepper motor driver and Serial communication system. The microcontroller here is a central processing unit to coordinate the previous three. Ultrasonic Range Sensor SRF05: The sensor operates in Mode 1 which uses a separate trigger and echo pins. These pins are connected to the PORT A of the microcontroller and are responsible for triggering and measuring the time of flight of the

In the article, “High-fidelity optical reporting of neuronal electrical activity with an ultrafast fluorescent voltage sensor”, an investigation of visual reporting of electrical signals in the brain is discussed. The authors express the importance of optical representation of electrical activity in the brain as an extremely useful tool for various neuroscience applications. This includes mapping the activity of genetically defined neurons in the brain and decoding neuronal communication. In particular
