In the past year, IDT has partnered with San Jose City College (SJCC) to deliver a project-based Internet of Things (IoT) course, with the goal of providing students with hands-on experience building an IoT solution. Students who took the course came from different tech backgrounds - some had little to no electronics experience and a few had never even heard of IoT. Nonetheless, they were eager to learn more about IoT and how it applied to their future career paths. In the course, they were given three “tracks” to choose from for their IoT project build and demonstration: Health/Wellness, Environment, and Location/Position.

Since most of the students had little to no experience in IoT, IDT provided each group with an SDAWIR03 sensor connectivity kit. The kits includes a sensor node that wirelessly communicates to the hub through IDT’s SensorShare™ 6LoWPAN protocol and is configured to display real-time data to a mobile device via Amazon® Web Services (AWS). Instead of the conventional route of just focusing on piecing together components and sensors with an Arduino platform, students had their hands on an entire system - from the sensors to the wireless communication, and data accessible via any AWS service module. This eased students into the technology so they could achieve their concept without worrying about having the needed technical expertise to get started.

“IDT's SDAWIR03 is a brilliant tool that accelerated the ability of my students to understand the underlying technology and quickly move onto building creative and compelling products,” said Cecil Lawson, Adjunct Professor, Entrepreneurship Program & Computer Information Technology, at the San Jose – Evergreen Community College District.

The SDAWIR03 kit uses the IDT® ZWIR4512 6LoWPAN wireless module to communicate relative humidity & temperature (using the HS3001) and gas flow (using the FS2012) measurement data to the kit’s 6LoWPAN WiFi Hub. The kit is pre-configured for AWS if the user chooses to monitor the data over the cloud. The mesh capability enables more sensor nodes to be added ad-hoc and extends each node-to-node range more than 30 meters. 

Once we provided this platform to the students, I was delightfully surprised by the different ideas and how they used the SDAWIR03 kit to demonstrate their concepts. They made IoT relatable to their real world problems; for example, from using the relative humidity/temperature measurement in a Wagyu-steak quality monitoring device to a smart prosthetic. Another group demonstrated the concept of a smart walking cane for the visually impaired, which featured haptic feedback that may one day communicate with crosswalk signal buttons and embedded solutions.


Working with these students has shown me that the possibilities are endless when it comes to designing for IoT. It was refreshing to see these ideas come to life and I’m excited to see more IoT innovation in future courses.
