This device is a digital USB ammeter that allows you to measure current automatically. It can provide quite accurate 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 insulated, which means that the sensor part is electrically disconnected from the USB part: you can measure any current including one coming from the mains, without risk of frying your computer. The module provides immediate reading on USB, and can also store measures on the device internal flash for later retrieval when connected again by USB.
This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
USB cables and enclosures to be ordered separately.
How can this unit be used to measure higher amperage than 10A? Is it possible to measure 20-50A DC (~15v)? Thanks!
@evansharp: No, but you can use a Yocto-milliVolt-Rx with a external shunt. See: www.yoctopuce.com/EN/article/transforming-the-yocto-millivolt-rx-into-a-usb-ammeter
