Introduction to AI + IoT
The convergence of Artificial Intelligence and the Internet of Things (AIoT) creates intelligent connected systems that sense, reason, and act autonomously.
What is AIoT?
AIoT (Artificial Intelligence of Things) combines IoT's ability to collect data from billions of connected sensors with AI's ability to analyze that data and make intelligent decisions. IoT provides the nervous system; AI provides the brain.
By 2026, there are an estimated 75+ billion IoT devices worldwide, generating zettabytes of data annually. Without AI, most of this data goes unanalyzed. AIoT bridges that gap.
IoT Without AI vs AIoT
| Aspect | IoT (Without AI) | AIoT |
|---|---|---|
| Data handling | Collect, store, display dashboards | Analyze, predict, decide, act |
| Alerts | Fixed thresholds (temp > 80°) | Anomaly detection (unusual patterns) |
| Maintenance | Scheduled (every 6 months) | Predictive (when failure is likely) |
| Automation | Rule-based (if X then Y) | Adaptive (learn from patterns) |
| Scalability | Manual rule creation per device | Models generalize across devices |
The AIoT Stack
Sensing Layer
Sensors and actuators: temperature, humidity, vibration, cameras, accelerometers, GPS, chemical sensors. These collect raw data from the physical world.
Connectivity Layer
MQTT, LoRaWAN, Zigbee, BLE, Wi-Fi, 5G, and satellite for transmitting data from devices to gateways and the cloud.
Edge Computing Layer
Local processing on gateways or devices using TFLite, ONNX Runtime, or custom ML models. Reduces latency and bandwidth.
Cloud AI Layer
Heavy model training, complex analytics, and historical data processing in the cloud (AWS IoT, Azure IoT, Google Cloud IoT).
Application Layer
Dashboards, alerts, automated actions, and business intelligence powered by AI insights from IoT data.
