IoT Ethernet Monitoring Kit

From sensor to Cloud, Microchip’s DM990101 and DM990004 Internet of Things (IoT) Ethernet kits powered by Medium One (software-as-a-service) offer an innovative, all-in-one IoT development package. Ethernet technology is becoming the most reliable and stable connectivity, enabling industrial IoT applications at an accelerated rate. This IoT kit uses an Ethernet LAN8740A and comes pre-loaded with Medium One Cloud service and mobile application (from Saritasa), as well as corresponding Microchip firmware. The firmware in the kit makes use of MPLAB®Harmony, FreeRTOS™, and WolfMQTT allowing for  quick-start IoT design. The Ethernet port is controlled by a 32-bit micro-controller which benefits from the 2 MB Flash of the PIC32MZ EF, providing plenty of memory space for the application code.

The security is addressed using WolfSSL features. The kit communicates with the Medium One Cloud over MQTT with TLS security, using both publish and subscribe topics. The mobile app communicates with the Medium One Cloud via REST over HTTPS.

The DM990101 comes with pre-configured code to support four sensors: pressure, temperature / humidity, air quality, and motion. In addition, hundreds of other different sensors can be plugged into the MikroElektronika mikroBUS™ footprint allowing for prototyping a large variety of IoT proof-of-concepts. MikroElektronika add-on boards are available for purchase here.
