8. IoT Open Source: An Overview
• Back-end Platforms
• Nimbits
• Java-based Data Management
Nimbits Server records and processes geo and time
stamped data and executes rules you define based on that
information. Rules can be calculations, statistics, email
alerts, xmpp messages, push notifications and more.
nimbits.io is an Open Source Java Library that provides an
easy way to develop JAVA, Web and Android solutions that
use a Nimbits Server as a backend platform. If you're
developing software for the Internet Of Things then good
news, we're giving you a head start.
