Today I make a research about Hall Effect Sensor.

The Hall Effect is the most common method of measuring magnetic field and the Hall Effect sensors are very popular and have many contemporary applications. For example, they can be found in vehicles as wheel speed sensors as well as crankshaft or camshaft position sensors. Also they are often used as switches. MEMS compasses, proximity sensors and so on.

What is Hall Effect?
A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications.

In a Hall effect sensor a thin strip of metal has a current applied along it, in the presence of a magnetic field the electrons are deflected towards one edge of the metal strip, producing a voltage gradient across the short-side of the strip (perpendicular to the feed current). Inductive sensors are just a coil of wire, in the presence of a changing magnetic field a current will be induced in the coil, producing a voltage at its output. Hall effect sensors have the advantage that they can detect static (non-changing) magnetic fields.

In simplest form, the sensor operates as an analog transducer, directly returning a voltage. With a known magnetic field, its distance from the Hall plate can be determined. Using groups of sensors, the relative position of the magnet can be deduced.

A Hall sensor is combined with threshold detection so that it acts as and is called switch. Commonly seen in industrial applications such as the pictured pneumatic cylinder, they are also used in consumer equipment; for example some computer printers use them to detect missing paper and open covers. They can also be used in computer keyboards applications that require ultra-high reliability.

Hall sensors are commonly used to time the speed of wheels and shafts, such as for internal combustion engine ignition timing, tachometers and anti-lock braking systems. They are used in brushless DC electric motors to detect the position of the permanent magnet. In the pictured wheel with two equally spaced magnets, the voltage from the sensor will peak twice for each revolution. This arrangement is commonly used to regulate the speed of disk drives.

In this journal, the owner will receive SMS if the pipeline have problem. So I want to share about LAN.

A local area network or LAN is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment. Computers and other mobile devices use a LAN connection to share resources such as a printer or network storage.

A local area network may serve as few as two or three users (for example, in a small-office network) or several hundred users in a larger office. LAN networking comprises cables, switches, routers and other components that let users connect to internal servers, websites and other LANs via wide are networks.

Ethernet and Wi-Fi are two primary ways to enable LAN connections. Ethernet ia a specification that enables computers to communicate with each other. Wi-Fi uses radio waves to connect computers to the LAN. Other LAN technologies, including Token Ring, Fiber Distributed Data Interface, and ARCNET, have lost favor as Ethernet and Wi-Fi speeds have increased. The rise of virtualization has fueled the development of virtual LANs, which allows network administrators to logically group network nodes and partition their networks without the need for major infrastructure changes.

Typically, a suite of application programs can be kept on the LAN server. Users who need an application frequently can download it once and then run it from their local device. Users can order printing and other services as needed through applications run in the LAN server. A user can share files with others stored on the LAN server; read and write access is maintained by a network administrator. A LAN server may also be used as a web server if safeguards are taken to secure internal applications and data from outside access.

In some situation, a wireless LAN, or Wi-Fi, may be preferable to a wired LAN connection because of its flexibility and cost, Companies are assessing WLANs as primary means of connectivity as the number of smartphones, tablets and other mobile devices proliferates.

WEEK 6 (FYP 1)

SURVEY FORM

Collecting data from survey form that has been distribute to resident. I have make a chart for each of the question below.

This is the information that i manage to gather from the survey form... ☺

2ND FINAL YEAR PROJECT BRIEFING

The second briefing was conducted in TTL 1 and the attendance is compulsory. The briefing was conducted by Dr. Jawad Ali Shah.

Date : 8 September 2017

Vanue : TTL 1

Time : 3.00 pm - 5.00 pm

Actually, this is a workshop on Introduction (Chapter 1) and Literature Review (Chapter 2) Writing.

In this workshop, the invited speaker have taught us about :

• Understand the significance of writing a good technical proposal for FYP 1.
• Understand the correct ways of writing a solid induction and literature review chapters in technical proposal.
• Write these two chapters with good writing skills.

This week i want to share about Digital sensor.

A digital sensor is an electronic or electrochemical sensor, where date conversion and data transmission are done digitally. These digital sensors are replacing analog sensors as they are capable of overcoming the drawbacks of analog sensors. The digital sensor consists of majorly three components: sensor, cable and transmitter. In digital sensors, the signal measures is directly converted into digital signal output inside the digital sensor itself. And this digital signal is transmitted through cable digitally. There are different types of digital sensors that overcome disadvantages of analog sensors.

Digital sensors are mainly used in water, waste water and industrial processes. They measure parameters such as pH, redox potential, conductivity, dissolved oxygen, ammonium, nitrate, SAC, turbidity.
