When traditional wired sensors aren’t practical, wireless industrial sensing can bridge the gap without the complexity of a full PLC system. In this article, IOThrifty walks through a real-world application where temperature and humidity had to be monitored on a moving machine using a wireless sensor, Modbus gateway, and relay controller. The result was a simple, self-contained control system with no Wi-Fi, PLC programming, or IT infrastructure required.

Monitoring asphalt temperature at every stage of road paving, from the plant to final compaction, is essential to ensure a durable, long-lasting surface. This article explains how and when to measure temperature using infrared tools, with a special focus on the IOThrifty PyroCouple sensor as a smart solution for construction professionals.

Measuring flow in liquid-cooled data center racks is critical as power densities increase and traditional air cooling falls short. This comprehensive guide explains how coolant flow is monitored in direct-to-chip and rear-door heat exchanger systems, including equations, sensor technology tradeoffs, and BMS integration. It is written for engineers responsible for designing and operating modern, high-density data centers.

A signal conditioner is the critical link between sensors and control systems, transforming raw, noisy signals into clean, standardized data engineers can trust. From amplifying microvolt readings to isolating circuits and linearizing temperature inputs, it ensures accurate and safe measurements in demanding environments. In temperature control applications, devices like the TxRail-USB, TxIsoRail, and I4P from IOThrifty deliver reliable, noise-free 4–20 mA or 0–10 V outputs that keep industrial systems running smoothly.

In liquid-cooled data centers, glycol keeps systems from freezing, but too much can make leak detection go blind. We tested how propylene glycol concentration affects conductive leak sensors and found that detection stops around 80%. See how your cooling loop compares.

Learn about the different types of temperature data loggers used across industries such as food, pharmaceuticals, HVAC, and manufacturing. Compare thermocouple, RTD, thermistor, and wireless models to choose the right logger for your monitoring needs.

High-density data centers are rapidly adopting liquid cooling technologies such as direct-to-chip cold plates and rear-door heat exchangers to manage racks drawing 15–30 kW or more. These systems often rely on propylene glycol mixtures in primary and secondary loops to transport heat safely and efficiently. However, introducing liquid to IT spaces introduces leak risk. Effective leak detection, integrated with a building management system (BMS) and tuned for water-glycol mixture, is now critical for uptime. Using IOThrifty solutions such as the LD1 Leak Detection System and LD Leak Detection Switch, engineers can deploy wide-area sensing, pinpoint leak location, and trigger immediate alarms to protect servers and maintain cooling continuity.
