The appeal of the DIY Data Logger #

Many engineers face the same problem: they need to extract data from a machine but management won't approve a $50,000 SCADA budget. The solution often is: "Let's build our own Data Logger with an Arduino".

Creating a data logger with Arduino is an excellent educational project. Here we show you the basics, but we'll also analyze why bringing this prototype to a real plant floor could cost you your job due to 24V interference and lack of galvanic isolation.
