Yoctopuce Yocto - milliVolt - Rx

  • 6900

Valarm Tools Cloud supports this milli Volt sensor adapter.

This device will let you connect a Valarm compatible connector device (like GSM sensor hubsWiFi sensor hubs or Ethernet sensor hubs) to any industrial sensor for monitoring and recording the status of your industrial assets. Your Industrial IoT, remote monitoring, and sensor telemetry information will be available at

With this sensor you can use Valarm Tools Cloud to receive alerts as well as map, graph, analyze, download, and forward your sensor data in real-time using our JSON & other APIs!

The Yocto-milliVolt-Rx device is a high precision USB voltmeter. It will let you measure very small voltages, down to a few dozen microvolts and up to a 2V max. This USB sensor device measures even when the voltages are generated by extremely weak sources due to very high impedance.

Typical applications include measurement of electro-chemical reactions (like pH and redox probes), low-voltage sensors (such as gas or chemical sensors) or Wheatstone bridges (e.g., load cells). It is also possible to use this device to precisely 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 measuring circuit is electrically isolated from the USB bus, which makes it possible to measure grounded voltages without the risk of creating a ground loop.

An enclosure for this sensor is available here.

A fancier (and much more expensive) enclosure is here.
