The SDAWIR evaluation kit demonstrates using the 6LoWPAN ZWIR4512 low power wireless module to communicate humidity, temperature, and flow sensor measurement data to the kit’s 6LoWPAN-WiFi hub. The hub functions as a WiFi hub, allowing a linked device to display and graph the measured data in real time.
The kit’s hub can also link to an end-user’s WiFi hub, which also allows any network device to display and graph the data in a web browser. The kit’s hub also permits sending the measurements to Amazon® Web Services with all the required permissions and setup of the data to be viewed worldwide. The end-user only needs an Amazon Web Service account.
The sensors, FS2012 flow sensor and HS3001 humidity and temperature sensor, are mounted in a 5cm clear plastic cube that contains a ZWIR4512 wireless module to communicate with the hub. The WiFi hub and the sensor cube are powered by a separate AC/DC wall mount adapter.
The hub utilizes a Raspberry PI Zero W to provide the WiFi hub function interfaced to the ZWIR4512 wireless module. The hub is using Raspbian LXDE Lightweight Desktop Environment. Raspbian is a Debian-based computer operating system for the Raspberry Pi. The hub micro SD card is fully loaded and ready for operation.
The IDT SDAWIR03 kit offers real-time sensor data collection that seamlessly integrates into sensor management services hosted on the Amazon Web Services (AWS) cloud, making it easier for engineers and software developers to design complex IoT solutions and applications, eliminating the need for specific device expertise.
The SDAWIR03 connectivity kit has been specifically developed for new and active AWS users who are interested in offering Sensing as a Service to their customers. The SDAWIR03 kit includes a sensor node module with real-time humidity, temperature, and gas flow sensors from which data is being collected. When additional SDAWIR03 sensor node modules are added, it will automatically connect via a mesh network based on IDT’s SensorShare™ 6LoWPAN protocol. The SDAWIR03 6LoWPAN hub connects to the AWS cloud from which the data can be visualized and analyzed using available tools such as ElasticSearch and Kibana. The 6LoWPAN wireless mesh connectivity uses an IPv6 address of each sensor module, integrating itself seamlessly into the existing infrastructure. IDT’s SensorShare wireless communication firmware in each SDAWIR03 kit has no license fee and no royalties, allowing resource and budget limited developers to focus on their end application.
This quick and easy to implement starter kit enables sensor data to link to the WiFi connected hub, and following a few steps to sign on to the AWS account, data mining and analytics services offered from AWS are ready to use.
The SDAWIR03 kit hub supports Over-The-Air updates (OTA) from the AWS site so the latest updates may be easily loaded to the kit. For example, the need to add 128-bit encryption security may be uploaded using the OTA update.
