Cloud Connectivity For Sensors


T


he proliferation of sensors and other connected devices in the Industrial Internet of Things for process management and


machine monitoring applications brings with it a number of challenges in certification and connectivity. Options for connecting nodes within the IIoT include the use of facility infrastructure like Ethernet or wireless or there are options to build Low Power Wide Area (LPWA) cellular networks. Cellular connectivity also enables IoT development in applications where access to wired or wireless infrastructure is limited.


❱ ❱ Multiple protocol cloud connectivity kits extend the


Industrial IoT beyond the server room


CLOUD CONNECTIVITY In addition to “private” clouds for large corporate networks, there are a number of commercial cloud services available for smaller users to connect into but how can this be achieved? One new development is a “cloud kit”, a complete hardware and


software reference design that allows the developers of embedded systems to quickly evaluate cellular connectivity options and build LPWA cellular IoT applications The Renesas Synergy AE-CLOUD2 kit simplifies connecting IoT sensor devices to enterprise cloud services using 4G/LTE Cat-M1 and Cat-NB1, also called NB-IoT, with fallback to 2G/EGPRS cellular networks. The kit’s functions accelerate prototyping cellular-enabled IoT devices for asset tracking, retail and agriculture monitoring, smart cities/utilities, mobile healthcare and industrial automation. The kit comprises a microcontroller (MCU) baseboard, tri-mode cellular modem with cellular and GPS antennas, Wi-Fi, Ethernet and various sensors such as lighting, microphone, temperature, humidity, pressure, air quality, geomagnetic, accelerometer and gyroscope. For cellular access, developers simply insert a SIM card with a data plan purchased from a local cellular carrier. The hardware kit’s software allows developers to connect to a 4G/LTE IoT cellular network and a cloud service provider, including commercial clouds such as Amazon Web Services, Google Cloud Platform, Microsoft Azure or Medium One Cloud. Users can visualise their sensor data on a customisable, password-protected dashboard.


CONFORMANCE The AE-CLOUD2 hardware kit ensures excellent EMC performance, having passed global RF emissions tests. In addition, the AE-CLOUD2 kit complies with global regulatory certifications for FCC, CE, RoHs, WEEE and Japan MIC. The kit’s fully optimised hardware/software saves developers months of design time and resources creating a scalable, energy efficient and secure end-to-end LPWA cellular IoT application that can be used anywhere in the world.
