When it comes to industrial wireless, many developers prefer IEEE 802.15.4 —especially when they’re looking for a reliable, low-cost, and low-power-consumption wireless technology option.More>>

A wireless radiation sensor network, a 3D Hall sensor, chemical sensors that can be embedded, and amazing DA systems: Meet the winners of this year's awards!More>>

A breakthrough technology uses temperature differentials to power sensor-driven building automation systems.More>>

Adding a wireless sensor network to fire extinguishers in large facilities or on sprawling campuses allows facilities managers to continuously ensure that the extinguishers are operational, present, and unobstructed rather than relying on a manual inspection every 30 days.More>>

Coupling RFID tags, ceiling-mounted antennas, and intelligent software enables NTT Multimedia Communications Laboratories to track its mobile assets in an effective and unobtrusive manner.More>>

High water-content items such as ice, water, produce, meat, and beverages can cause problems for some RFID technologies. This article discusses the differences between available RFID technologies and describes an HF-enabled energy harvesting sensor IC and HF RFID reader.More>>

This article describes the considerations involved when integrating wireless connectivity based on IEEE 802.11 (Wi-Fi) into a sensor system that monitors a storage unit.More>>

What do a rugged shock recorder, a vibration dosimeter, a tiny IR imager, wireless sensor nodes, an array of different sensors, energy harvesting devices, and feature-packed data recorders have in common? All of them won a Best of Sensors Expo Award at the 2010 Sensors Expo.More>>

Hybrid wireless systems—incorporating multiple types of wireless technologies—offer significant benefits for collecting data from large, geographically dispersed networks, such as those in the oil and gas industry.More>>

Here's how supercapacitors—double-layered capacitors with the ability to store far more energy than a traditional capacitor—can be used in conjunction with a small solar cell to power a wireless sensor node.More>>
