The OPC Foundation requested a live demo for the Hanover Fair presenting the connection between sensors and Microsoft Azure using OPC UA PubSub MQTT.
As sensors, we decided to use the XDK from Bosch Connected Devices and Solutions. That small device contains a series of sensors i.e. temperature, light, accelerometer, acoustic, gyroscope, humidity, etc… Over wireless communication, we collected these sensor data in our COLIGO Edge Device (www.coligo-tech.com), then pushed these to Azure using PubSub over MQTT. Since the Matrikon Flex OPC UA SDK provides the functionality, the implementation was rather simple.
As a result, this demo was shown and presented both on the OPC Foundation and Microsoft booths and the feedback has been extremely positive.
