Connect any machine to the cloud. Realtime machine data monitoring. Analytics and machine learning.
PPM IoT Machine Counter

The Lean Projects PPM IoT Central is a Microsoft Azure based web service to connect Azure IoT event hub data with Dynamics 365 for Finance and Operations, Enterprise edition or other ERP systems.

Machine data is collected using low cost, standardized hardware interfaces based on popular and open source Raspberry Pi and micro controller hardware platforms. Counter sensors deliver raw telemetry data at a configurable frequency to an Azure IoT event hub.

The PPM IoT Device Central offers real-time machine performance monitoring, stream analytics and device configuration. Through a REST API, shop floor data collection terminals can be integrated.

The open hardware platform allows to connect a wide range of sensors through a standardized electrical interface.
