GDE Technologies, LLC specializes in developing real time I/O applications that provide ease of use at modest cost . The applications are engineered around our concept of using MS Excel® Workbooks programmed to distribute the tasks of sensing and actuation to programmable microprocessors (Arduino’s ESP 32’s, etc). We have developed are an automated sample preparation unit for laboratories, a laboratory autosampler for liquids and gasses, various repetitive mechanical testers, a process controller, flow analyzers, and some custom sensors. We develop the software portion of applications using MS Excel® wworkbooks. These workbooks are matched with custom sensors and actuator that are slaved to the Workbook® slaves to complete the picture.
