Data loggers are small, battery-powered devices used to sense and store information in different situations. They include a microprocessor, data storage, one or several sensors and they can record information for a very long period. However, some data loggers do not include sensors, but have ports that allow a sensor to be connected. They are

Angle sensing has always been challenging particularly in industrial and automotive environment because of the need for precise and accurate sensing at high speeds. Allegro Microsystems developed the A1330 an integrated circuit angle sensor that works based on magnetic Circular Vertical Hall (CVH) technology. Unlike other angle sensors Allegro’s A1330 does not require a concentrator

Now you can use your smartphone to check how clean the air is, measure the freshness of food or even the level of your blood sugar. This has never been so easy. All credit goes to the new spectrometer sensor which is developed at the Eindhoven University of Technology and can be easily attached to a
XMOS is one of the many companies that has ventured in voice recognition technology. They created the VocalFusion XVF3500 device, the first voice processor to have true stereo-AEC support in a far-field linear microphone array solution. Voice recognition is a relatively new technology for consumers which we came to know with Siri, google home, Alexa

The researchers of North Carolina State University in the US, lead by Jingyan Dong, have developed a new technique for directly printing flexible, stretchable metal circuits. The innovative technique can be used with multiple metals and alloys. It is also compatible with existing manufacturing systems which can integrate this new printing technology effortlessly. The technique uses the well known electrohydrodynamic printing
MicroZed is a low-cost development board from Avnet, the makers of the $475 ZedBoard and the entry level MiniZed development boards. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation or combined with a carrier card as an embeddable system-on-module (SOM). The MicroZed processing system is
