im manisha here.. i need a ppt on data logger andriod.. i kindly request you to send me the ppt on data logger andriod as soon as possible

Data Logging

2. Introduction• A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors.
3. Which is faster?
4. “Does the inclined track with a certain angle affect the acceleration and velocity of a moving object?”
5. Carrying out the experimentTitle : Acceleration-Cart on an inclined track with different angleObjective• Investigate how acceleration of object depends on the angle of the inclined tract by using the motion sensor• Determine the angle of the inclined track for each different height, h• Use the software to plot the graph of position, velocity, and acceleration versus time for each trial.

7. Equipment and apparatus Track Retort stand and clampCart Ruler
8. Set-up of equipment and apparatus
9. ProcedureComputer setup• The PASPORT USB interface is plugged into the computer’s USB port.• The motion sensor is plugged in into the USB interface. The PASPortal window is automatically launched.• Appropriate DataStudio configuration is chosen.
10. Equipment setup• The equipment is set up as shown in figure.• The height of the point of release of the cart from table surface is measured. Different heights (8cm, 12cm and 16cm) are used in this experiment. The length of the track is also measured to obtain the inclined angle. Length of track, l Height, h
11. • The motion sensor is placed at the raised end of the track so it can measure the motion of the cart as it moves down the inclined track. At the top of the motion sensor, the icon ‘Cart’ is selected.• Cart is hold at the mark “15cm” of the track. When it is released, the data is recorded. The experiment is repeated by changing the height to 12cm and 16 cm to obtain 3 sets of data.
12. Record Data• The button Start is clicked and the cart is released so that it moves down the track.• The button Stop is clicked before the cart hits the end stop of the track.
13. Analyze dataVelocity graph• The smooth part of the velocity is highlighted. Then, linear fit is selected from the fit menu. The slope (the value of m) for the cart is then recorded.Acceleration graph• The flat part of the acceleration is highlighted. Then, linear fit is selected from the fit menu. The slope (the value of m) for the cart is then recorded.• The value for the slope of the velocity to the mean of acceleration is compared.

17. Angle: 10.8Graph
18. Questions:• Describe the situation where an object slide down at different inclined angle and the forces that involved in it.• What are the forces that acting upon an accelerating object on inclined track and draw a diagram to show the forces, plus state how the acceleration is formed?• From the result, describe how the acceleration is affected by different inclined angles?• What are the constant variables in this experiment?• What precaution/ precautions you took when doing this experiment?
19. Experiment’s conclusion Component Component parallel to the perpendicular to the plane, mg sin θ plane, mg cos θ As the θ increase, -mg sin θ increase -mg cos θ decrease. -Acceleration and velocity increase.
20. Why the water flow faster at the upstream compared to the water flow at the downstream ?
21. The position, velocity Three different graphs can be and acceleration of plotted at the same time the cart can be determined andmeasured accurately Less work needs to be done by using the motion the students sensor. The changes of the data and graph can be observed immediately, Discussion allowing students to make any can be take changes or detect and overcomepart after the any errors in the experiment. experiment withoutwasting more The experiment can be repeated time many times to obtained the accurate readings
22. ConclusionEach of these experiments was veryquick and easy to set up. Using thesimplest mode of operation of thesoftware means that almost noknowledge or experience of datalogging is required.
