This device is a digital USB ammeter that allows you to measure current automatically. It can provide quite precises digital measures (2 mA, 1%). It works with direct current (DC) as well as alternating current (AC) for which it provides the RMS value (5 mA or 3%). 

This device is isolated, which means that the sensing part is electrically disconnected from the USB part: you can measure any current including from the mains, without risk of frying your computer. 

The modules provides immediate reading on USB, and can also store measures on the device internal flash for later retrieval when connected again by USB.
