I. BACKGROUND OF THE STUDY

BACKGROUND OF THE STUDY

The researchers found it challenging to use the traditional measuring tools, so they made the decision to incorporate the laser meter and the traditional meter to develop a new type of measuring tool. Measurements have always been essential to humans. We use it to evaluate phenomena that can be quantified into numbers, such as time, which is measured in seconds, mass in kilograms, and distance in meters. Although these measurements can be performed without assistance, it is more efficient to use devices that can provide accurate information. (Eden, 2019)

In 1993, the first laser distance meter was introduced. It was large and heavy; however, it measured every detail accurately. The aim was to assist people who require accurate measures, including workers. Today's laser distance meters come in a variety of sizes and designs, and some of them can even measure objects using images. (Bwauters, 2019).

The first steel tape measure was invented in 1829 by James Chesterman. Hoop skirts for dresses were created using flat metal wire invented by Chesterman. Chesterman moved to create tape measures after hoop skirts fell out of demand. He had a spherical leather box with tape measures inside. In 1868, Alvin Fellows invented the first tape measure with a spring lock. When the tape measure is pulled out, you may lock it in place. However, Fellows' tape measure was pricey and took some time to gain popularity. (Cabral, 2021).

The proposed product is a multi-functional meter that combines the functions of a distance meter and an angle meter. It has an ultrasonic sensor that can measure distances up to five meters while ensuring accurate measurements through the use of a laser diode. Furthermore, it utilizes the MPU6050 gyro accelerometer to enable an angle meter feature. This feature can easily and accurately determine surface angles, similar to a traditional level bar tool. It also features a microSD card port for data transfer. Additionally, it supports environmental sustainability by incorporating a rechargeable battery that is supported by an Android charging connector, which not only reduces battery waste but also extends the usage life of the device. This product is innovative because it combines all these functions into a single device, which makes it more convenient and efficient for users.

The evaluation of ultrasonic sensor and laser meter is purposely to help the students and professionals by giving them a versatile, and easy-to-use tool that makes their work more accurate and productive. Although measuring tape or a ruler are very convenient, they still require a few menial tasks. The researchers wanted to come up with a device that would be relatively simple to use and can acquire the measurements accurately in a very short time. This product will be a valuable tool for drafting students and professionals, and it will have a positive impact on the drafting technology industry.
