Yoctopuce, USB sensors and actuators

Meet Yoctopuce

Yoctopuce designs, manufactures and sells USB devices to let your computer sit in the real world, not in the cloud. Our USB modules are tiny, easy to install and easy to drive programmatically. Among them you will find:

Yocto-4-20mA-Rx

Yocto-4-20mA-RxSmall USB module to read very precisely the output of two 4-20mA sensors. The device can convert the current measure to the equivalent physical measure on the fly, and includes a built-in datalogger.

And what's smoking ?

Polling vs. Callback

The Yoctopuce API provides several ways to communicate with Yoctopuce modules: polling, value change callbacks, and periodic callbacks. We mentioned them all from time to time in this blog, but we never took time, until now, to present in details these different techniques. So let's have look :-)

Using Xively or Emoncms with a YoctoHub

When you simply want to display a physical measure with a Yoctopuce module, there are several solutions: You can write your own program to display the sensor data, or use the embedded data logger with our command line API to export the data. But there is an even simpler solution: configuring a YoctoHub to post the values in the cloud. We natively support Xively and Emoncms, and this week we explain how to configure a YoctoHub to use these services.
