People who are visually impaired or even blind can now read the text from a book, smartphone screen or other surfaces. This is possible thanks to a voice-activated device that attaches to the frame of virtually any glasses. The OrCam MyEye uses an advanced 13 megapixel optical sensor that captures an image of the user’s […]
Illuminated keyswitch series integrates LED
C&K has developed an illuminated keyswitch series that offers smooth, positive tactile feedback with a clear tactile sound for superior ergonomics and ease of use. The D6 Series illuminated keyswitch features an integrated LED, reducing costs and simplifying the design of the illumination path. As a result, the D6 Series is used in a wide […]
LVDT/RVDT/resolver simulator module occupies just one PXI slot
Pickering Interfaces launched its model 41-670, a single module that can function as an LVDT, RVDT or resolver simulator. Occupying just one PXI or LXI chassis slot, the programmability of the module means that it minimizes the amount of hardware required. Also, since it sits in a PXI chassis alongside a customer’s other instruments, additional […]
How can you quickly integrate an Ozone sensor into your final design?
First, you must have an ozone sensor that meets your application’s requirements. Must haves could include: Measurement Range 0 to 20 ppm Lower Detection Limit <0.1ppm Resolution <0.1ppm Accuracy <± 2% of reading Small Size with Low Profile (15x15x3mm) Long Life (10 years expected life) Fast Response (15 seconds typical) Long Term Stability (50 ppm […]
Anti-vandal pushbutton switch offers an extended durability in shorter housing
C&K has launched an IP67-rated anti-vandal pushbutton switch with a short-body. Designed for spaced-constrained applications, the ATPS19 Series pushbutton switch offers a nearly 40% reduction on the body length as compared to the standard ATP19 version. Rated to more than 200K electrical life cycles, the ATPS19 Series is commonly used in alarm, safety & security […]
How do you track an elephant?
Very carefully might be your first response but there is a technical answer as well. The technical answer involves a design challenge called ElephantEdge to create the world’s most advanced tracker to protect elephants in their natural habitats from poachers, trophy hunters and habitat destruction. Supported by Hackster.io, an Avnet community, and Smart Parks, a […]
LVDT electronics, Part 2: Interface circuitry
The interface electronics for the LVDT must excite the primary-side winding with a sine wave and then demodulate the two resultant secondary-side waveforms; modern ICs make this analog-signal process fairly straightforward. Part 1 of this FAQ looked at the basics of LVDT excitation, demodulation, and waveforms. This part looks at two standard ICs which implement […]
LVDT electronics, Part 1: Excitation and demodulation
The interface electronics for the LVDT must excite the primary-side winding with a sine wave and then demodulate the two resultant secondary-side waveforms; modern ICs make this analog-signal process fairly straightforward. The first two parts of this LVDT article (see References) looked at the LVDT transducer itself, along with its attributes and history. This second […]
What is the Air Quality Index? Pt 3
AirNow and PurpleAir report the Air Quality Index (AQI) using different methodologies. With two different techniques to measure air quality (See Pt1), how does the data from the two approaches correlate? While AirNow’s monitors cost tens of thousands of dollars and require significant infrastructure and trained personnel to operate, PurpleAir’s sensors may only cost a […]
What is the Air Quality Index? Pt 2
With over 90 forest fires raging along the West Coast, you may feel safe and think you do not need to check the air quality index (AQI) if you don’t live in that region. Think again! A recent satellite image shows that the smoke already extends all the way to Michigan. Don’t smell any smoke? […]
