When we geek try to cook a nice chunk of meat, the tricky part is the cooking itself. Instead of sitting idle while the meat cooks, we go read something on the iPad, code some stuff or even to talk with the guests rather than watching a meat in the oven. And at the end, the meat is often overcooked. But this is gonna change. Our new recipe, using a Yocto-Thermocouple and Raspberry Pi, solves the issue. The Raspberry Pi will monitor the meat temperature for us, and send an e-mail as soon as the ideal temperature is reached. And long life to the smartphones !
This week we are proud to announce the availability of two new products, long awaited by our industrial customers as well as DIYers. The first one, named Yocto-Thermocouple, is a tiny module capable of sensing the temperature at the end of two thermocouple cables, ideal to measure very high and fast-changing temperatures, as well as to measure the temperature of liquids or food for instance. The second one, named Yocto-CO2, measures carbon dioxide in ambiant air and will tell you about the quality of the air you are breathing.
There is one question which comes back rather often in the Yoctopuce team. Here it is: How to make Yoctopuce modules work in the middle of nowhere, in the back of the garden, for instance?. Indeed, it is unlikely to have an electrical outlet in the back of the garden, without even talking about a USB connection. In the opposite, there is sunshine, and we can easily make sure that we also are within a Wifi range. We are not solar specialists, but Yoctopuce modules consuming an average of 125 mW, it shouldn't be all that difficult to make them work with a solar panel...
A few weeks months ago, we announced the Java API. It is at last available, even better we have two versions of the Java API. A standard Java version and a version for Android. You can download them from the usual location. As we have already written about the standard Java library, we are going to talk about the specificities of the Andoid library.
All of our USB sensor modules perform their measurement with the help of digital sensor chips, which are factory calibrated. It's our recipe to guaranty the announced precision of our modules, even when the sensors are moved away. However, we have recently introduced in all our sensor modules an additional adjustment function, allowing your to perform a correction to the measures on the fly. So, what's the need to correct a measure if it is already good? Doesn't this recalibration risk to reduce the measure precision rather than to enhance it?
