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.
