How did you work with Weka to build an IoT solution to address these challenges?

Weka built the fridges itself and we built all the smarts to make it a smart fridge. So, sensors in the fridge talked to our software running on Raspberry Pi, a very small computer installed in the fridge and running Microsoft Azure – and tells [Azure] the current location, temperature, or whether anyone added a vaccine to the machine. We compile these telemetrics and send them to the cloud, and you can monitor the fridges from one dashboard.

So, say I'm in a village in Africa and I happen to have a Measles vaccine. Five miles down the road there's a patient who needs it, but that particular location doesn't have the vaccine. From my center console, not only can I see [that] I could send one down there, I can see it hasn't been compromised by temperature and [it hasn't reached its] expiration date yet. It's a great way to let doctors save money in general on vaccines, but also to track them better and save more lives, frankly.
