USB DrDAQ device for teachers and technicians

Saelig has introduced the USB DrDAQ, a combination scope/data-logger/IO board that offers a collection of 15 I/O channel in a compact, low-cost device designed for hobbyists, teachers and technicians.

Software provided with the unit provides an easy-to-use 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, four digital I/O ports, three 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 analyser with the ability to measure voltages up to +/-10V.

The device's 10-bit D/A output features a 10-bit signal generator - a standard function generator, but also an arbitrary waveform generator (AWG) - so customised waveforms can be created.

An RGB LED can be used to display any colour 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 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 even be integrated into other programs in C, C++, Microsoft Excel and National Instruments Labview.
