The Yocto-milliVolt-Rx device is a high accuracy USB voltmeter. It lets you measure by USB very small voltages (down to a few dozen of microVolts, and up to 2V max), even when they are generated by extremely weak sources (very high impedance).
Typical applications include measurement of electro-chemical reactions (e.g. pH and redox probes), low-voltage sensors (e.g. gaz sensors, etc), or Wheatstone bridges (e.g. load cells, etc). It is also possible to use this device to accurately measure the voltage drop across a shunt to measure high currents.
The input circuit of this device uses a very low bias current amplifier (typ. 0.2 pA). The measure circuit is electrically isolated from the USB bus, which makes it possible to measure grounded voltages without risk of creating a ground loop.
For measuring the weakest signals (e.g. pH measurements), we recommend to use the BNC variant of this product, which features a BNC connector to use with coaxial cable, to avoid electromagnetic interference.
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.
My Windows 10 computer does not recognize Yocto-milliVolt-Rx-USB.
I installed VirtualHub.windows.31315 (64bit).
Can you create a driver for Windows 10 and make the istallation instruction?
@volt-win10: Our products don't need any drivers. Your Yocto-milliVolt-rx is supposed to work on any version >=Windows XP, including Windows 10 64bits, as soon as it it plugged. Make sure that you are using a proper USB cable, not a phone USB charging cable, then contact Yoctopuce support.
Hi there I'm a newbie, and don't know much about this product.
My questions are:
I assume you plug it into your laptop usb port-- this provides the power to the device and also the means to access what is going on on the circuit board.
1. Where do the wires, which will serve as a voltage probe, connect to the circuit board? Where do I solder these wires onto the circuit board?
2. Can I write a Powershell program to monitor the voltage values given by the circuit board. Powershell has full access to the .NET classes (I think full access, unless it uses .NET core in which case it has access to a subset on the .NET programmable infrastructure.) My question is: Would I be able to import a module or dll ie. an assembly into Powershell, and use this module to access the voltage values output by the device? Thanks.
@gaz: you would simply put the measurement wires in the terminal block, as illustrated in the user manuel (yes, we do provide a manual :-) Regarding access from PowerShell, you are perfectly correct: this can be done via the .Net proxy DLL, as described in this article: https://www.yoctopuce.com/EN/article/the-yoctopuce-library-as-a-net-assembly
We used the Yocto-milliVolt to fabricate a prototype of a breathalyzer integrated in a smartphone screen. The Yocto-milliVolt work perfectly. Easy to use and implement. For more info, here is the article on the breathalyzer:
Thanks to you for making such great products!
