Gateway design, firmware, and industrial sensor networks — real-time data from factories, warehouses, and fleets.

Sensors rarely fail outright — they drift, and drift triggers no alarm

The devices are still online, the data still arrives on schedule, the charts still look smooth, and nothing has alerted for months. The only problem is that the numbers stopped being correct a while ago. This is the failure mode that slips past every routine check — and one very concrete example shows why: a CO₂ sensor's self-calibration assumes the room empties out once a week.

Attacking the power grid with AI: what changed is not the way in, but who can afford the trip

2025 produced two events that look contradictory: a cyber-espionage campaign in which AI handled 80–90% of the hands-on intrusion work, and a dam whose valve control was taken over for four hours because of one weak password. The gap between them is what is actually changing for physical infrastructure.

Edge AI: when to run inference on-device, when to send it to the cloud

Global AI infrastructure spending doubled in a single year, and inference — not training — now accounts for most of that spend. But the more important question for an IoT system isn't "where is AI cheapest to run" — it's four concrete factors: latency, bandwidth, cost, and sensitive data.

AI + IoT in Smart Clean Vegetable Farms — sensors, models, and the automation loop

A VietGAP-certified vegetable farm no longer means the farmer stays up monitoring soil moisture or irrigating by feel. We break down the architecture combining multi-sensor IoT, an AI vision model for early pest and disease detection, and a closed-loop control system running at the edge — plus how VietGAP traceability becomes a natural by-product of comprehensive logging.

LoRaWAN, MQTT or NB-IoT: choosing the right connectivity protocol for industrial IoT

Three names that appear together in almost every IoT design discussion — but they are not three alternatives for the same job. LoRaWAN and NB-IoT are wireless radio protocols that determine range and battery life; MQTT is a messaging protocol that runs on top. Understanding which layer each solves helps avoid some expensive architectural mistakes.

Reading part of a massive point cloud file: classification, octrees, and COPC for LAS/LAZ/PTS data

A LiDAR LAS/LAZ scan of a plant or a road corridor can weigh dozens of GB and contain billions of points. Most real tasks — fetching only ground points, only one structure in an area, or a low-resolution preview — don't need the whole file. How LAS/LAZ/PTS organize classification, bounding boxes, and octrees, and how PDAL, Entwine, and COPC exploit them to load only the points you need — cutting system load and speeding up large-scale 3D processing.
