All serious athletes know the importance of staying properly hydrated. The hDrop is a smart wearable device that can help with that. It measures your hydration status in real-time from your sweat, measuring changes in electrolytes and body temperature to notify you what action to take.
The hDrop lets you know when you are starting to get dehydrated. It can also track your sweat rate. Like what you see? You can find this project on Kickstarter.
