Story

Story behind the project

Library's self-study area is a good place for people to read and learn.But noise has always been a serious problem in library management. According to a survey results, 83% of the readers reported that the noise generated by other readers is the main source of noise in the library environment.Think about it, if you are reading a book or studying for your coming exams and there is a person nearby who keeps making noise, it will be difficult for you to concentrate.So, a team of students from the Hebei University of Technology decided to design a Noise Reminder Device. When the noise level is high, the machine will remind people to keep quiet by lighting up lights.

Project Introduction-Functions, How to use

They designed and built a mockup of a desk to simulate a library desk, with a noise sensor placed under each of the four legs, and four LED strip lights placed on the tabletop, the LED lights, and the noise sensors can monitor the noise condition in 4 directions. LEDs also have different light-emitting frequencies according to the volume of the noise.

Process and steps

1. Group brainstorming

2. Select the sensor

3. Write code and debug

4. Design 3D appearance structure renderings

5. Use a laser cutting machine to cut appearance structural parts

6. Test

7. Assembly project hardware, assembly appearance
