This device is a digital USB voltmeter that allows you to measure voltage automatically. It can provide quite accurate digital measures for low DC voltage (0.01 Volt accuracy), but works as well for higher voltage, including AC, up to 250V (RMS), with an accuracy of 3%.
This device is isolated, which means that the sensor part is electrically disconnected from the USB part: you can measure any voltage difference between -250V and 250V, 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 module is the equivalent of the Yocto-Volt, but with a USB type-C connector. Both versions can be connected to a USB A, Type C or Micro-B host with the appropriate cable.
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.
