Sensors are increasingly in our lives, microprocessor technology is evolving and open source hardware is becoming widespread. Preparation of experimental setups using open-source hardware reduces research costs. Arduino is an open source development platform which is operated with an open source software. It consists Atmel AVR microcontroller, circuit elements for interfacing, a 5 volt regulated power and a 16MHz crystal oscillator. With 10 bit ADC, it can read 0-5V voltages in 1024 steps. There are at least six analog inputs and 13 digital input-output pins, which can meet the channel requirements of a soil mechanics laboratory. Together with the "do-it-yourself" civil movement, the use of these platforms by young engineers in particular will gain experience that can be helpful in different applications. This study explains design and development of a low cost and open source data acquisition system for soil mechanics laboratories. The main advantage of making laboratory scientific equipment by using open source hardware is that, shared design promotes a better design as the scientific community can contribute to its design. In modern geotechnical laboratories sensor readings are essential for many setups such as consolidation, uniaxial compression, triaxial compression and shear box tests. Moreover, some tests need temperature and humidity conditioning. In the setup, Arduino Uno model was used as a microcontroller. Sensors with a 5 volt supply can be connected directly, and a booster circuit is added to the circuit for sensors requiring a 10 volt supply. The data of sensors having 0-5 volt input signal can be directly digitized. For sensors with millivolt output such as load cells, a driver circuit is added. The code is written in the C ++ language. The acquired data are tabled on an Excel sheet and it is possible to process the data for specific needs.
