So, the computer based data acquisition and storage for field data is very important for precision agriculture development. The automatic data storage allows to eliminate the human reading and type errors, to reduce data losses and no synchronism readings among different sensors, in addition assure different frequency readings with precise intervals This present research had for main objective to develop and evaluate a data acquisition and storage system based on personal computer for analogical sensor (load cells and potentiometer) and GPS receiver (Global Positional System). The main objective of this research was to develop and evaluate a low cost acquisition and storage data system for analogical sensors (load cells and potentiometer) and GPS receiver and also realize a comparative economical analysis between the actual data acquisition system (Micrologger CR10X) and the proposal system.
