While at Rutgers University I was lucky enough to collaborate with a team of researchers on a low power wireless sensor project, at the time called the Owl Platform. Along with the team, I performing hardware design and PCB layout and worked with a PCB manufacturer and assembly facility to get 1,000+ built. 

The sensors were designed to last 10 years on a coin cell battery, and detect light levels, detect the presence of water, measure ambient temperature, and monitor doors and windows.

In 2013 we had a Kickstarter, and even got a mention in TechCrunch. Although ultimately we did not meet our funding goal, the team kept working on the technology, and it was a great experience.
