Project Overview

Water leaking and irregularities in pipe flow cause cascading problems in residential plumbing systems around the world. Design an effective water detection system for the purpose of detecting leaks and irregular pipe flow using sound and vibrations. This product should be universal to all water district-based companies.


Proof of Concept

Team 3’s purpose is to create a device that can detect water leaks using a microphone. The microphone is attached to the main of a residential house and must be able to detect leaks in the house behind the water main. The device must then be able to send the pertinent data to the end user to act upon.


Final design

The design specification of the project called the drip which is a water flow detection system are basic requirements for the manufacture of the drip. Hydronar presented certain functions that the drip must have as well as having to follow the hazard identification requirements. The categories and requirements such as sensor type, program, durability, safety will be important to be able to build the drip with all the necessary functions for the use of the consumer and following the safety parameters. The characteristics of the drip are durability, quality, affordability, functionality, instability, usability and safety. The drip has minimum durability of 3 years and it must be stored in a box when is not in use. The quality of the drip will be based on the fact of the parts such as sensors, housing material, and all the components are well selected and that the drip pas the tests during the design and manufacture. The affordability of the drip will be affordable for most consumers since it is an important product for homeowners and the price is based on similar products. The main functionality of the drip is to detect water leaks in the pipes of a water system, and the installation of the drip is basic so that the buyers can install it with some basic tools. The usability of the drip is easy to use since it is programmed to be used with a Bluetooth system on your smartphone or an electronic device and most people have experience using smartphones. Lastly an important safety characteristic, the drip will not cause property damage and the materials used in the drip are not toxics and they are recyclables. The purpose of the project is to be able to detect leaks in the pipes of a water home system and to inform the users through the drip that there is a lot of water flow or is dripping a pipe so that they can act and repair it. The drip will be beneficial for consumers because consumers can avoid property damage such as small floods, appliances damage and short circuits. Consumers can also detect a water leak and repair them, so
they can reduce their water bill and have more control of the water system of their own homes.



  • Design Solidworks concept model and testing
    • Sketch the final design for the water flow detection device.
    • Simulate the final design using FEA analysis with galvanized steel and iron as materials.
  • Material Inspection Report
    • The materials need to meet the HID standards and PDS requirements.
    • Sensors and others parts need to be complete and check its functionality.
  • 3D Printer
    • Convert the Solidworks file to STL file and brought to the 3D printer for production.
  • Assembly
    • Install 3D printed housing, microphone and vibration sensors into different pipe sizes and then to the breadboard connections.
    • Connect the 9-volt battery and attach the galvanized steel and iron pipe segments to a home water system such as pipe, hose and kitchen sink.
  • Software programs testing
    • Revise that the Arduino program work properly.
    • Ensure that the Bluetooth is on, and the collecting data device receives data via Bluetooth.
  • Prototype Testing
    • Attach the galvanized or iron pipe into a main home water system pipe or any internal hose pipe to conduct the test in three different intervals full flow, half flow and no flow of water by controlling the water source handle.
    • Perform the previous test with different pipes sizes with a range of 1 inch to 1.5 inch.
    • Collect data from the different pipe sizes and analyzed to find a relation respect to the pipe sizes, materials and the interval flows.
  • Approval
    • Yes, the prototype is complete and is ready to be presented.
    • No, start over from the assembly step, and adjust the program and try different pipe sizes, materials and reading data sensors.

As I’ve progressed through my engineering career, I have moved away from being a tinker garage mechanic and turned into an engineer who diagnoses first, analyzes the problem and uses logic to achieve the solution with the most utility.

Most difficult engineering project was working with Finnegan Erickson and Associates Engineering Consultants where I helped lead a project for the Wilton Rancheria in Stockton California. I had to develop CFD models for a glass dome that has two humps and uneven heights. I was also in charge of some of the hydroponic piping design work and domestic water line routing.

I helped charter FarmHouse fraternity at the University of Nevada Reno and received the Outstanding Chapter President award for the 2017-2018 school year.

Born in Long Beach California and grew up in Las Vegas, Nevada

Goals after graduation: Work as a mechanical engineer and start my own business

Goals Future: Pass the PE test and receive PE after hours certification and eventually open my own firm.


Nathan Smith

I have been involved in engineering project since I was in high school. I studied my entire high school life in a school with 30% of the time in manual work such as working in cars, machine shops and home plane shechts. In college, I studied Mathematics and I was part of a team working in a project to fix the conditioner issue in cars. I was just working in the mathematics calculations and I rarely get involved in the design concepts and PDS for the project. I am from Peru which is in South America, next to Brazil. I would like to work and finish the project with my team for ME 451 and contribute with my basic skills even know English in not primary language. After graduation, I would like to work in a company like TESLA because I love cars and I want to design new components to improve design and efficiency in cars. I have my own space with tools and cars to play around and learn how they work to apply that knowledge in the future after I finish school. In addition, I want to live in U.S and not going back to Peru because I think I will have more opportunities in U.S than my home country.




Tyler Kinney

Tyler is a senior undergraduate student in the Mechanical Engineering program of the University of Nevada, Reno from Las Vegas, Nevada. In terms of engineering skills, he has developed the ability to effectively communicate information, improved on teamwork in diverse groups, expanded on his knowledge in various engineering fields, and improved on critical thinking aspects for problem solving while attending UNR. Tyler is proud of the progress he has made in the restoration of a 1991 Toyota MR2 Turbo in terms of its drivetrain, cosmetics, and electrical components. Throughout the restoration process, he used analytical techniques to evaluate issues that arose based on symptoms the vehicle exhibited and determined proper courses of actions in order to solve the problems. For example, when the vehicle wouldn’t start, Tyler began troubleshooting the issue by first outlining the requirements for an engine to turn over before assessing each essential aspect carefully and ultimately discovering the underlying problem. His current goal is to finish his undergraduate study and receive his bachelor’s degree. Upon graduation, Tyler hopes to enter the automotive design industry and further expand on his lifelong passion for cars.



Hung Le

Hung’s most challenging engineering project that he has been involved in is the ENGR 100 hovercraft project in freshman year. Some of the obstacles he faced was many of his team member’s ideas conflicted with one another. Towards the end of the semester when the hovercraft was completed, the biggest difficulty Hung faced was using trial and error to modify the team’s hovercraft to meet the criteria for an A. Throughout Hung’s college career, he has improved various engineering skills to succeed in his courses. Problem-solving, communication, effective teamwork and the ability to work under pressure were some of his most improved areas of skills. Interning at Arrow Electronics over the summer is Hung’s biggest accomplishment that he is proud of. The application of knowledge throughout his college career helped him succeed in impacting the company. An example of when Hung applied his ability was during his internship where he used M.O.S.T to generate an engineered time study for his department. After researching the technique, he created a time study on the current efficiency of the department and then conducted another time study on what areas of focus can be improved. Hung is born in Vietnam, but he moved to Las Vegas, Nevada where he was raised. Hung’s current goals is to do well in his last college career, apply for jobs and internship for the following semester and develop strong connections with recruiters. After graduation his goals is to hopefully work for a firm somewhere near Las Vegas to keep in touch with his parents and relatives.
