Rain sensor

Wiper blades are devices used to remove rain, debris, snow, and ice from the windscreen. They are also known as windshield wipers or windscreen wipers. They are used by most driven machines including motor vehicles, watercraft, train locomotives and aircraft. They are usually a legal requirement for most of these crafts. A wiper usually consists of metal arm balanced at one end and a long rubber blade attached to the other end. The metal arm is mostly powered by electric motor. The rubber blade is swung over the glass, back and forth. This action pushes water, snow and other matter causing poor visibility. The speed is usually adjustable. Blade wipers also have other applications. Some automobiles are fitted with blade wipers on the back window screen as well. This type of blade wipers are commonly found in station wagons or estates, hatchbacks, minivans, sport utility vehicles and other automobiles with vertically mounted rear window screens that are prone to dust accumulation. Modern automobiles are now being equipped with rain sensing wipers that detect the presence and quantity of rain by utilizing a rain sensor. This sensor automatically controls the speed of the wiper blades according to the amount of rain experienced. There is a variety of wiper blades in the market. The thing to keep in mind when shopping for a wiper blade is that it…

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,…

A flood is a rising, overflowing body of water (lake, river, ocean, etc.) that rushes onto typically dry land. Flash floods are extremely common during heavy downpours for towns near a body of water. Most usually, these towns are warned about the potential dangers of a flash flood because meteorologists have the remote sensing, which can come in radars, rain gauges, and satellites, to predict the chances of floods. Meteorologists and hydrologists can keep track of precipitation using these…

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…

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…

to feed their stock. Grazing and pasture becomes abundant during raining seasons. In the drier months, grazing fields wither, but pasture recovers shortly during the raining season, and animal population surges during this season. In time, climate change conditions such as rain shortages and prolonged periods of drought, coupled with a population upsurge in the herding communities increases to such a degree that overgrazing lead to an irreversible land deterioration. Thus, the carrying…
