Project Background and Need:

Developing a proximity and noise sensor/alarm for lumber/construction/outdoor occupations to increase workplace safety in hazardous working environments. Lumber and construction jobs have some of the highest injury/fatality rates and account for many cases of hearing loss. By having a proximity sensor for the workers and the equipment along with a noise sensor, this issues may be mitigated.

Problem Description/requirements (List of high-level functionality you expect to see in the end product):

Product should be able to warn individuals and equipment operators of being "close" and then "dangerously close" to each other. An easy-to-implement design that users can access easily (i.e. clip on to a helmet). Users should be able to understand warnings the device emits. These devices should be removable for versatility. If possible, a noise sensor should be able to indicate various levels of dangerous hearing ranges.

Required Skills / Desired Competencies (in order of importance):

• Embedded hardware and programming

• Analog circuit design

• PCB design and layout

• Power electronics and power systems

• Networking

• Mobile app development

• MATLAB and Simulink
