An Open Hardware Electronic Controller for Motorized Rotary Injection Valves Used in Flow Injection Analysis

Abstract

This work presents the design, development and the implementation of a motorized injection valve used in Flow Injection Analysis. The built prototype has been developed based on the open hardware emergent philosophy, software and firmware, thus helping the development of a free and independent science. This policy creates a platform of open projects that feed each other, contributing to scientific and technological development while sharing knowledge. The proposed design project can be modified to implant it in other devices or projects according to the needs of each one. Also, the open project can be a great help as teaching material in Universities, since open hardware projects are fully described and documented.
