Saelig Company Inc.'s USB DrDAQ is a combination scope/data-logger/IO board with 15 I/O
channels. Software provided with the unit provides 100kHz-bandwidth
oscilloscope and datalogger, with extra input and output capabilities straight
out of the box. Built
into the USB DrDAQ are a microphone, light sensor, RGB LED, oscilloscope and
resistance inputs, 4 digital I/O ports, 3 sensor ports, a pH/redox sensor input
and a signal generator output. The unit is powered from the USB port so there
is no need for an external power supply. USB DrDAQ samples at 1MSa/s and can be
used as a single-channel 8-bit 100kHz oscilloscope or spectrum analyzer with
the ability to measure voltages up to Â±10V.
USB DrDAQ's 10-bit D/A output
features a 10-bit signal generator - a standard function generator, but also an
arbitrary waveform generator (AWG), so customized waveforms can be created. An
RGB LED can be used to display any color for a variety of indicator purposes.
Two of the I/O ports can be used as pulse counting inputs, or PWM (pulse-width
modulation) outputs. The sensor ports can be used with a range of temperature,
humidity and oxygen sensors, or with custom sensors built by the user.
USB DrDAQ will find its way into
a wide variety of applications from education to research for signals at audio
frequencies and beyond. It is supplied with a free Windows Software Development
Kit (SDK) with fully documented function calls to control all aspects of the
device, so it can be integrated into other programs in C, C++, Microsoft Excel
and National Instruments LabVIEW.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
