MOXIE IoT uses industry standards and cutting-edge technology to create a monitoring solution which provides their manufacturing customers with a single source of truth. Their iOS iPad app equips their customers to visualize and analyze industrial factory data in real time. Discover how they use a time series database, MQTT and Ultra-Wideband to accurately measure and track any object, device, personnel or machinery. In this webinar, Dr. Austin Gurley will dive into: MOXIE’s approach to app-centric asset monitoring Their ability to help customers streamline operations while bridging the gap between hardware and software How a time series database improves customer experience by enabling them to query, filter and parse their data Techniques for performing Flux queries in iOS Swift

Why InfluxDB?
• Why InfluxDB?
• Time-series for IoT (c.f. DynamoDB)
• NOT end-to-end (c.f. AWS IoT)
• Relevant data filtering unloads app
• Why InfluxDB Cloud?
• Manage accounts and access
• Interactive query builder
• Clear storage pricing (c.f. AWS)

iOS Swift
• Why iOS?
• Connecting to Real World devices
• Focus energy on one platform
• Tools for
• 3D visualization
• Map-based visualization
• Input/Output (BLE / MQTT / etc.)
