Pico Technology has launched the USB DrDAQ data logger, offering 15 channels in a compact low-cost device that is suitable for a range of applications, including education and research.

The data logger is supplied with full versions of the Picoscope and Picolog software so that all of its capabilities are ready to use straight out of the box.

The circuit board of the USB DrDAQ includes a microphone, light sensor, RGB LED, oscilloscope and resistance inputs, four digital I/O ports, three sensor ports, an oscilloscope input, a pH/redox sensor input and a signal generator output.

The unit is powered from the USB port so there are no batteries or external power supply required.

The USB DrDAQ is a replacement for the parallel-port DrDAQ.

The higher transfer rate of USB allows the USB DrDAQ to act as an oscilloscope for signals at audio frequencies and beyond.

Many new features have been added in the USB DrDAQ, notably the combined function generator and arbitrary waveform generator.

The RGB LED can display any colour.

Two of the I/O ports have a pulse-counting function when used as inputs, and a pulse-width modulation output capability.

The sensor ports can be used with Pico Technology’s range of temperature, humidity and oxygen sensors for the DrDAQ, or with custom sensors built by the user.

The USB DrDAQ is supplied with a free software development kit (SDK) with fully documented function calls to control all aspects of the device, so users can integrate it into their own programs.

The kit includes example programs in C, C++, Microsoft Excel and National Instruments Labview.

The SDK, Picoscope and Picolog are compatible with Microsoft Windows XP, Vista and Windows 7.
