Sensirion recently released the SPS30, a particulate matter sensor with both a serial interface and an I2C interface. So, obviously, we didn't have to wait for long before someone asked us whether we could interface it with Yoctopuce modules.
If you have already tried to build a control panel interfaced by USB with many ON/OFF buttons, you know that it's not as simple as it may seem. Not only the multiplication of buttons makes the wiring process quickly complex, but if you are limited to 5 or 8 inputs per module, the number of interface modules that you must use increases rapidly. A way to improve these two issues consists in multiplexing several buttons on a single analog interface, and this is what we are going to show you today.
While we were making improvements to the Yocto-PWM-Rx for our previous post, we noticed that this device has considerably changed since its conception in order to cover more use cases than the once planned initially. To help you navigate into all these possibilities, we summarize in this post the different working modes.
The Yocto-Watt is a small module which is very convenient to measure by USB the voltage, the current, and the instantaneous real power of an electric circuit. As it is also able to integrate the power to compute the total energy for a given lapse of time, some users also employ it to measure the energy that a system consumes, and we have recently improved this feature.
As several countries are starting to alleviate the containment rules, we are receiving many requests concerning our infrared temperature sensor, the Yocto-Temperature-IR. Indeed, the possibility to quickly and without contact detect people who may be sick seems interesting. But is it as easy as it seems?
