Internet of Things with Fexingo: Connected Devices, Sensors, and Industrial IoT

Episode 81 of Internet of Things with Fexingo dives into a surprisingly high-stakes application of connected sensors: monitoring the curing of poured concrete. Lucas and Luna walk through a specific case from a highway bridge project in Tennessee, where embedded IoT temperature and humidity sensors replaced the standard 'cure for 7 days and hope' approach. They explain why concrete strength depends on keeping it within a narrow temperature window for days, how wireless sensors cut the risk of premature loading, and how one contractor saved roughly $400,000 in rework costs on a single 12-month project by catching a cold-weather pour that would have turned brittle. The conversation zooms out to the broader shift from prescriptive to performance-based specifications in construction, and why sensor-verified curing data might become a legal standard. No hype, no jargon—just a real-world example of how cheap, ruggedized sensors are quietly changing one of the oldest industries on earth.

Episode 80 of Internet of Things with Fexingo dives into a critical application for the booming solar energy sector: using IoT thermal sensors to detect and predict hotspot formation on photovoltaic panels before they lead to fires or permanent damage. Lucas and Luna examine a real incident at a 50-megawatt solar farm in California where a single hotspot cascaded into a three-acre brush fire. They walk through how arrays of low-cost infrared thermopile sensors, combined with edge-based machine learning, can monitor temperature gradients across thousands of panels in real time. The hosts discuss the specific physics of hotspot formation—partial shading, cell mismatch, and microcracks—and how predictive algorithms can flag panels for maintenance weeks before failure. They also touch on the economics: each sensor node costs under $200, while a single fire can cause millions in damages and downtime. This episode offers a concrete look at how a mature sensor technology is being repurposed to solve a fast-growing problem in the renewable energy transition.

In this episode of Internet of Things with Fexingo, Lucas and Luna explore how connected sensors are preventing catastrophic gas explosions in underground utility vaults beneath city streets. They focus on the specific case of Washington D.C., where a 2023 incident nearly caused a major blast, and how a network of methane and hydrogen sulfide sensors now monitors over 1,200 vaults in real time. The hosts break down the sensor technology—electrochemical cells and catalytic beads—and explain how the data feeds into a central dashboard that alerts crews within seconds. They also discuss the economics: each sensor costs about $150, versus potential liability in the millions. Lucas and Luna debate whether this is a model that should be mandated nationwide, and touch on the challenges of retrofitting older infrastructure. The episode closes with a forward-looking question about integrating these systems with smart city platforms.

Offshore wind farms lose millions when ice builds up on turbine blades, forcing shutdowns and risking catastrophic imbalance. Lucas and Luna explore how a German startup, BladeSense, mounts piezoelectric vibration sensors inside the blade's trailing edge to detect ice formation before it's visible. BladeSense's system, deployed on 200 turbines in the North Sea, correlates sensor data with weather models and automatically triggers a controlled de-icing cycle using internal heating elements — reducing downtime by 60 percent in winter months. They discuss the physics of blade icing, why traditional camera-based detection fails at night, the cost of a single unplanned shutdown (up to $50,000 per turbine per day in lost revenue and repair risk), and how this technology is spreading to onshore wind farms in Scandinavia and Canada.

Wildfires ignited by power lines are a growing threat in dry, windy regions. In this episode, Lucas and Luna explore how utility companies are deploying IoT sensor networks to detect early signs of equipment failure — arcing, conductor sag, vegetation contact — before they spark a fire. They walk through a specific case: a California utility that installed tens of thousands of line-mounted sensors across high-risk corridors, and how the data flows from detection to dispatch in under 30 seconds. Along the way, they discuss the technical challenges of operating sensors at extreme temperatures, the role of machine learning in distinguishing nuisance events from real threats, and why this approach is more effective than traditional patrols. By the end, you'll understand how a combination of accelerometers, current transformers, and weather stations can turn a passive power grid into an active fire prevention system — and why regulators are starting to mandate these technologies.

In this episode of Internet of Things with Fexingo, Lucas and Luna explore a critical but often overlooked application of IoT sensors: preventing underground gas migration from old landfills. When organic waste decomposes in a sealed landfill, it generates methane and carbon dioxide. That gas doesn't just stay put — it can migrate laterally through soil, accumulate in basements or utility vaults hundreds of feet away, and cause explosions. Lucas walks through a real case in Southern California where a retired landfill caused a house explosion in 2022, killing two people. He explains how low-cost IoT methane sensors, deployed in monitoring wells around the perimeter, now provide continuous real-time data that alerts operators before gas reaches dangerous concentrations. Luna asks about the trade-offs between electrochemical and infrared sensors, and Lucas details how the industry is shifting to solar-powered LoRaWAN nodes that reduce maintenance costs by 80 percent. The episode also touches on regulatory pressure from the EPA and how these systems tie into broader environmental monitoring networks. A reminder that listener support keeps the show ad-free and independent.

Grain elevators are among the most explosive industrial environments you've never heard of. In this episode, Lucas and Luna dive into the science of grain dust combustion and how IoT sensor networks are now stopping explosions before they start. They examine a 2025 incident at a Nebraska co-op that triggered a multi-state review, and walk through the specific sensors — temperature, CO, relative humidity, and vibration — that can detect the early warning signs of a smoldering pocket inside a grain silo. The hosts also discuss the economic math: a single sensor node costs about $150, while an average elevator explosion can run $8 million in damages and lost grain. They look at why adoption has been slow despite the clear ROI, and what the Biden-era infrastructure grants did to accelerate retrofits in the Midwest. A focused, numbers-driven look at a niche but deadly industrial risk that IoT is quietly solving.
