Image sensor

section I will discuss what the above code do. First, LinkIt ONE initializes the Ubidots account, then the sensors, Wi-Fi or GPRS, the location and finally the serial port. To minimize battery consumption, I did not use the GPS antenna to detect and acquire automatically the location. I manually added the location of the device in the codes using latitude and longitude coordinates. The Eco-Smart Can device will try to update the collected data to Internet on the Ubidots…

This mechanism implemented with two sesnors which can detect a surface under the robot and move the robot accordingly. If the edge is detected on a platform by right sensor the robot will turn to its left and vice versa. When the robot detects the edge on both the sides it moves backward untill it doesn’t detect any edge and then moves to the right side a little and repeats the above process. Line following robot : Now, lets design a line following robot, for that, I need to pick a 50 ext block…

Design and Simulation of Microcantilevers for Sensing Applications Abstract- MEMS is the integration of active and passive elements on a single chip, which combine electronics, electrical as well as mechanical elements to use in sensing and actuation. MEMS technology used in sensing applications with use of basic mechanical elements such as microcantilevers, beams, diaphragms, springs, gears and so on. In this research paper, microcantilevers are used as basic elements for design of Sensors.…

1. Abstract The Passive Optical Networks (PON) is the network which is most popular in fiber network access systems. The abstract states the actual concept of Passive optical Network it's importance. It also implies the Definition and explanation of ONT(Optical Network Terminal), ONU, FTTH-BPON and FTTH-GEPON systems in FTTx premises. 2. Objectives The key objectives of the lab are : • Learning Fiber to the home - BPON and Fiber to the home - GEPON systems. • To process the layer 2…

A number of caries detection devices are available in the market today. Each of these is based on a certain underlying physical principle such as X- Rays, Visible light, Laser light, Electrical current and Ultrasound (Pretty, I. 2006). The four basic characteristics that need to be looked at for comparing devices are explained below. 1. Reliability Reliability ensures a procedure that is consistent, stable and dependable with minimal error on repeated measurement of the same variable (Pretty,…

The communication protocols used in connecting sensors form a network for collecting sensory information called BSN. Patients who are going about their day to day activity can receive quality health monitoring in real time by us of BSN. The BSN nodes are attached to these patients. On a predetermined period, the BSN collect health information such as pulse, blood sugar level and temperature and transmit it to a remote medical aid. This way, the medical personnel are able to keep up to date with…

In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal…

time without disturbing life. What is meant by that phrase is that when a photo is taken, that precise moment is forever captured to be revisited at the viewer’s leisure. When a photographer takes an image it is very different than when a friend tells you, “ Lets take a selfie!” Although, both a photographer and one capture that moment in time, a photographer tries to tell a story or a message as to look who I’m with; which with in itself is telling a story. Professional photographers want…

There are many kinds of lens filter available on the market these day. The most common lens filter is the Ultraviolet filter, which protects the lens from dust, water, scratch, and prevent the Ultraviolet ray (sunlight) to burn the camera sensor. However, there is a kind of lens filter that is useful for Portrait photography called Circular Polarizing Filter or CPL. The main function of CPL filter are reducing reflections, enhancing colors, and increasing contrast. To reduces reflections, just…

1.1.1 Types of Sensor Networks Terrestrial WSNs: - In Terrestrial WSNs, nodes are distributed in a given area either in a pre-planned manner (sensor nodes are placed according to optimal placement, grid placement, 2-d and 3-d placement models) or in an ad hoc manner (sensor nodes are randomly placed in the target area by dropping it from plane). After all battery power is limited and it cannot be reenergized, terrestrial sensor nodes must be provided with a maximum power source such as solar…
