Back in March, we teamed up with Sparkfun, Google Cloud, and Hackster to bring our community the IoT Without Limits contest. The challenge? Develop an innovative end-to-end wireless sensing application using Helium and Google Cloud IoT.

Fast forward four months later, 385 registered participants, and many late nights spent hacking together projects, the curtain has finally closed on the contest. We received amazing submissions from developers who went above and beyond to put their creativity and technical chops to the test, building IoT applications that actually solve real-world problems.

A big thank you to all of the participants for stepping up to the challenge and participating in the contest.

So, which participants will walk away with the $16K USD in cash prizes and the free trip to San Francisco? Our judges will carefully review submissions in preparation for official winner announcements July 25th.
