INTRODUCTION
In this world, technology can change lives. Everyday people discover
different new ideas to solve a problem easier, (See Appendix A). This part of
innovation is applied to electronics. Measuring instrument is mostly used by
workers especially in the construction (See Appendix B). This study presents a
measuring tool that capable to measure the distance, volume and area fast after
the user is placed on the flat surface. With Laser Distance Measuring Tools, one can
achieve more accurate measurement readings especially at extended lengths and in
a shorter period. Laser distance measuring tapes are one of the fastest and most
accurate ways to collect measurements, especially if you have multiple measurements
to take during the same job or day (See Appendix C).
BACKGROUND OF THE STUDY
Previously, when you measured a room, you would get your tape
measure. Standard tape measure can be hard to use. Often, you will need helping
from another person to get measure accurately and you maybe use a third person
service. As well, it will not retreat all the way if you get the tape measure wet or
dirty. In the past, the standard measuring tape does not give an exact a result even
on a flat surface. This old method of measurement conducts a computation.
Timely, to try getting the maximum accuracy with measuring tape, you need two
persons, or the tape will cause of headache your head. The old fashion tape isn’t
accurate. This old method of measuring causes more effort and tiring, So the laser
distance measure makes the measuring more efficient and convenient to use. This
device gives the measurement more accurate and easier to use.
OBJECTIVES
The main purpose of this research is to design and develop a
portable laser distance meter that must be capable of measuring the distance of
an object through the use of m703A laser sensor. The specific objective of the
study are list down below:

To design and develop a laser distance meter that is capable of
measuring the length of electrical conduit and pipeline.

To create a portable integrated laser distance meter that announces
the output reading of the laser distance meter using text to speech
sensor.

To use ANOVA(F-Test) statistical tool in determining the efficiency
of the integrated laser distance meter compared to the commercial
laser distance meter in measuring the distance of an object.
STATEMENT OF THE PROBLEM
Measurement is necessary in everyday life. Even the very earliest
civilizations needed measurement for purposes of agriculture, construction, and
trade. People developed a tools that used in measuring, until they improved it in a
device that measure distance. In the industry, Laser distance meter is that
measure length used specifically in the construction field (See Appendix B). These
parameters are sufficiently needed in estimating and designing an electrical design
especially to those who work in construction field and the like.
This research study aims to determine the effectiveness of designing laser
distance measuring device that can measure the length. This study aims to answer
the following questions.

Are the measurements accurate?

How efficient the device?
SCOPE AND DELIMITATION
The scope and delimitation of the study is focused on integrating a
laser distance meter. The integrated laser distance meter will be compare to a
commercial laser distance that measure the displacement of an object. This study
is limited on measuring the distances using m703A laser sensor to provide an
accurate distance measurement, specifically in electrical conduits and pipeline of
2nd floor SFC Building, University of the East Manila.
The laser distance meter has only limited up to 40 meter range
exceeding values will not be measured. The device unit is in meter. The device is
not capable of measuring the volume and area of an specific object.
APPENDIX A
In science or human geology, population growth is the expansion in the
quantity of people in a population. Many nations, incorporating numerous in SubSaharan Africa, the Middle East, South Asia and South East Asia, have seen a
sharp ascent in populace since the finish of the Cold War. The dread is that high
populace numbers are putting further strain on normal assets, sustenance
supplies, fuel supplies, business, lodging, and so forth in a portion of the less lucky
nations. For instance, the number of inhabitants in Chad has at last developed
from 6,279,921 out of 1993 to 10,329,208 out of 2009 further stressing its assets.
Vietnam, Mexico, Nigeria, Egypt, Ethiopia, and the DRC are seeing a comparable
development in population.
Worldwide human population development adds up to around 83 million
every year, or 1.1% every year. The worldwide population has developed from 1
billion of every 1800 to 7.616 billion out of 2018. It is required to continue
developing, and gauges have put the aggregate populace at 8.6 billion by mid2050, at that point begin declining until 2100. Numerous countries with quick
population growth have low expectations for everyday comforts, while numerous
countries with low rates of population growth have exclusive requirements of living.
APPENDIX B
A measuring tape is an adaptable ruler and used to quantify separate. It
comprises of a lace of material, plastic, fiber glass, or metal strip with direct
estimation markings. It is a typical estimating device. Its structure considers a
proportion of incredible length to be effortlessly conveyed in pocket or toolbox and
grants one to gauge around bends or corners. Today it is universal,
notwithstanding showing up in smaller than usual frame as a keychain dandy, or
trinket. Surveyors use measuring tapes in lengths of more than 100 m in the
construction field.
. Use of measuring tool in Construction
1. Find horizontal lengths (overhead) for determining rain gutter¹ length.
2. Measure distances from roads¹ and property lines to comply with local
building codes.
3. Determine amounts of structural materials (studs, plywood) needed for
construction.
4. Determine insulation requirements (volume needed).
5. Determine offsets needed for septic systems.
6. Determine trench, hole depth.
7. Determine amount of sheetrock to cover surfaces
APPENDIX C
With Laser Distance Measuring Tools, one can achieve more accurate
measurement readings especially at extended lengths and in a shorter period of
time. The longer that a measuring tape measure is extended, the harder it is to get
an accurate measurement. You have to worry about slack in the line or applying
too much tension on the tape and stretching or possibly even breaking it. You have
to line up the marks directly with the starting point. Even temperature can affect
your measurement when using traditional measuring tapes. Laser distance
measuring tapes are one of the fastest and most accurate ways to collect
measurements, especially if you have multiple measurements to take during the
same job or day.
Most laser distance measuring tools offer easy operation, and some
advanced models offer many more features and functions depending on what
you're wanting to accomplish. The distance measuring tool projects a laser which
looks very similar to that of a laser pointer. Simply point and press the button. It
will automatically measure to where the laser is pointed. With some models you
can select whether you want the length of the tool itself included in the
measurement or not, which is handy in situations where its advantageous to have
the rear of the unit against a wall or post for example. Most laser distance
measuring tools can manage basic calculations like addition, subtraction, area,
and volume. They can also store previous measurements, depending on the
model, into internal memory. Some laser measuring tools will track minimum and
maximum measurements. You can automatically transfer between different units
of measure such as feet, inches, tenths, meters, etc. And some lasers have a builtin tilt detector to take measurements at an angle, ranging anywhere from 0% to
100%.
