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.
