We recently showed you how Yoctopuce serial interfaces could make computations on the values read in order to present them directly in a form that the user can use. Today, we show you a similar feature which is also present on some of our analog electrical sensors.
The Yocto-SPI documentation contains an example to interface the AlphaSense OPC-N2 particle counter. Since then, Alphasense has released a new model, the OPC-N3, and the commands to query it are slightly different. This week, by popular request, we explain who to make the OPC-N3 work with a Yocto-SPI and we take this opportunity to introduce a small innovation.
There are probably not many measuring devices based on a physical phenomenon as unstable as barometric altimeters. And yet, they are still widely used, for want of anything better. Technological progress even makes it possible to go even further in the accuracy of this technique, which seems to defy common sense. Welcome to the Yocto-Altimeter-V2!
To open the door to new applications, we extend our range of analog voltage measuring tools. The newcomer, the Yocto-MaxiMicroVolt-Rx, is the most accurate of all, and it can measure minute voltages, in the order of the micro-volt. Let's see what this means...
More than half of the Yoctopuce devices in the Environmental Sensors category perform temperature measures in one way or another. Why are there so many ways to measure the temperature and what are the advantages and disadvantages of each method?
