Water Leak Detection: From Spot Sensors to Industrial Leak Panels — The Complete Quality-Tier Buyer's Guide
Every water-leak detection method compared across the quality ladder — from $3 resistive spot pads to addressable leak-locating cable panels — with the coverage trap, conductive-vs-nonconductive liquids, locating, and price side by side. Find the tier your assets actually need.
Current & Power Sensors: From CT Clamps to Revenue-Grade Meters — The Complete Quality-Tier Buyer's Guide
Every common current and power sensor compared across the quality ladder — non-invasive CT clamp to metering-class revenue meter — with current-only vs true power, accuracy class, interface, safety, and price. Find the tier your job actually needs.
Soil Moisture Sensors: From Resistive Probes to TDR — The Complete Quality-Tier Buyer's Guide
Every common soil moisture sensor compared across the quality ladder — corrosion-prone resistive probe to research-grade TDR — with lifespan, calibration to true volumetric water content, interface, and price. Find the tier your job actually needs.
CO₂ Sensors: From MH-Z19 to Vaisala — The Complete Quality-Tier Buyer's Guide
Every common CO₂ sensor compared across the quality ladder — from hobby NDIR to traceable industrial CARBOCAP — with the "eCO₂" trap, accuracy, drift, interface, and price side by side. Find the tier your job actually needs.
Temperature & Humidity Sensors: From DHT22 to Vaisala — The Complete Quality-Tier Buyer's Guide
Every common temperature & humidity sensor compared across the quality ladder — hobby to hardened industrial — with accuracy, drift, interface, lifespan and price side by side. Find the line where "cheap enough" stops being safe for your job.
What Can You Build on LoopString’s Free Tier? 4 Real Automation Projects
Four complete automation projects you can build on LoopString's free tier — a grow tent, fermentation chamber, utility-room watchdog, and cold-storage tracker — using just 1 device, 8 sensor slots, and 24-hour history.
From Prototype to Production: Scaling an IoT Greenhouse
The journey from monitoring one greenhouse with a free-tier Pi to managing 10 zones across a commercial operation. A real scaling story that mirrors the LoopString pricing ladder.
Monitoring a Small Brewery: 15 Sensors, 3 Pis, One Dashboard
How a small craft brewery uses 3 Raspberry Pis, 15 sensors, and LoopString to monitor fermentation, cold storage, and the brew house from a single dashboard.
Edge vs. Cloud PID Control: Latency, Safety, and Why It Matters
Why running PID controllers on the Raspberry Pi edge instead of the cloud is a critical safety and latency decision for IoT process control.
