Part 1 of this four-part blog addressed air quality monitoring in cities and populated areas. Less densely populated areas such as a rain forest may require different approaches. In addition, water quality monitoring in outdoor locations as well as clean drinking water from processing stations provide additional sensing opportunities. Part 2 will address these areas. […]

How does an acoustic camera work and what’s it good for?
Acoustic cameras consist of microphone arrays used to locate and characterize sounds. There are a variety of microphone array structures to support specific analysis needs. Some acoustic cameras also have an embedded visual camera to supply an image over which the acoustic localization information can be presented. Acoustic camera application examples range from analyzing noise […]
Torque sensor provides analog and Ethernet outputs
New low-capacity models of Sensor Technology’s non-contact torque sensors offer accurate measurement down to 200mNm (0.2Nm), for applications such as precision and high-speed robots, medical devices, prostheses and implants, small drives, and micro motors. The new TorqSense SGR 510/520 torque sensors cover capacities from 0.2Nm to 1Nm, making the full range 0.2Nm to 13,000Nm. The […]

What are ten key parameters of audio system performance?
Ten key parameters of audio system performance include efficiency, frequency response, total harmonic distortion, intermodulation distortion, phase distortion, transient distortion, transient response, dynamic range, sound pressure level, and sound power level. This FAQ reviews how each of these parameters is specified and measured and closes with a look at how safe sound levels are specified […]
When to use sound pressure and when to use sound intensity measurements
Sound pressure, sound intensity, and sound power are three different ways to quantify sound. This FAQ begins by defining each one, looks at various types of measurement techniques that can be used to quantify them, presents a range of international testing standards for measuring sound, looks at instruments used for measuring sound pressure and intensity, […]
IoT light sensors measure either ambient or UV light
L-com recently announced the expansion of its line of IoT light-detection environmental sensors. The sensors gauge either ambient or ultraviolet light. The new sensors assist in the use of IoT data collection to make process control more efficient and lower building and process costs. Applications for light-detection sensors include greenhouses, agriculture, solar farms, labs, factory floors, manufacturing, […]
How can sensors protect vulnerable areas? Part 1
Clean air and water are essential for life. Protecting these valuable, essential elements, starts with sensors to detect threats from intentional or unintentional contamination. Today, available sensing technologies target different locations/areas to ensure the safe ongoing supply of fresh air and water. Using a variety of different sensing techniques, the key to broad and localized […]
How can sensors help an electrolyzer provide green hydrogen?
Energy storage is an essential part of the pursuit for the increased use of renewable energy sources such as wind, solar, geothermal and hydroelectric power. Electrolyzers allow hydrogen-based storage and avoid the reliance on batteries and their raw materials such as lithium, graphite and cobalt that are frequently sourced from China. When renewable energy sources […]
How do sensors improve home appliances? Part 2
Part 1 of this blog discussed sensors in the laundry room in washing machines and dryers. In the kitchen, similar to the laundry room, basic functions can be designed in using established sensing techniques. In the typical home, the refrigerator is the second-largest consumer of electricity (13.7%), with the air conditioner being number one. So, […]
