The DataDuino data acquisition (DAQ) kit is designed to be robust and configurable but relatively simple. It is based upon the Arduino platform (using the Uno bootloader). It stores data to an SD card and uses a real time clock for accurate timestamping. The fastest resolution is 1 second sampling, up to 99999 second sampling.

Data acquisition is always useful to monitor a wide range of projects. Knowledge is power. With data, you can monitor your system, make changes and record how well they do and generally improve the things you are working on. Also having real data and real facts is vital if we are trying to prove an effect.

Data is stored onto an SD card. A real time clock is used to time-stamp the data and the output is a .csv file.

Sample Arduino code for a datalogger unit is provided here and can be built upon.

This is a K-type (or J-Type) thermocouple amplifier which can be used to amplify the tiny voltage from a thermocouple to a higher voltage, readable by a microcontroller. Thermocouples can be used to measure very high temperatures, but they only output a very low voltage, hence the need for this amplifier.

This kit is based upon the AD8495 precision K-type thermocouple amplifier, or the AD8494 J-type version. The board requires a 5V supply and gives a linear output of 5mV per degree C. The circuit board contains filtering for the standard amplifier configuration. It can be used to measure temperatures up to 1000C.

This kit is available here for £10 (including UK P&P)

We have created a range of modular power monitors, regulators and displays. The basic modular unit has been designed for pedal generators within the range of 12-35V DC and up to 20A DC, but bespoke units for different voltage and current ratings are available.

Options are available to display power, regulate the power level or record data to a computer or SD card.

Here is the overview of the options available and their features.

These units are available ready built and tested. Please This email address is being protected from spambots. You need JavaScript enabled to view it. to discuss your project and how we might be able to help.

The battery voltmeter is a plug-in voltage monitor for 12V battery systems. This could be used in a car, caravan, on a boat or for your off-grid renewable energy system.

The kit includes a switched 4 digit LED display to accurately show the battery voltage, an enclosure for displaying the voltage in an appropriate place and a 'cigar lighter' style socket to plug in and power the display.

Accurately knowing the battery voltage is very important for managing lead acid battery based systems. See our battery worksheet for more information on batteries and their state of charge.

The Battery Voltmeter is available as a kit for £12 (including P&P within the UK).

Or it is available fully built for £18 (including P&P within the UK).
