Build Future-Ready Skills in IoT & Cloud Integration

IoT & Cloud Integration Mastery Program

Modern engineering products are no longer just hardware. A soil sensor is useless without a dashboard a farmer can check on their phone. A factory motor is incomplete without real-time health telemetry flowing to a maintenance team. A fleet vehicle is dumb without a connected backend tracking every kilometre. Embedron Module 2 is built around exactly that reality.

Over 45 carefully sequenced days, you'll move from a single ESP32 publishing data over Wi-Fi to architecting a full IoT product stack: field devices speaking LoRa across kilometres, a Raspberry Pi acting as the edge gateway, an MQTT broker bridging to a cloud platform such as ThingsBoard, time-series storage in InfluxDB, beautiful dashboards in Grafana, and a Flutter mobile app that pulls it all together for the end user.

Every concept is taught through hardware first. You will solder, flash, debug, sniff packets with a logic analyser, configure TLS certificates, run signed OTA updates, and ship an APK to your own phone. By the end of the module, you don't have a stack of slides - you have a working, deployable IoT product aligned to your chosen industry track.
