How to calibrate a CO2 sensor?

By mvuilleu, in Measures and Misc, may 01,2015.

CO2 sensors are increasingly popular to monitor air quality at home and in business premises. So much so that we tend to forget that the measures are based on rather advanced technologies, requiring some precautions if we want to make sure that we obtain valid measures. So, do we need to calibrate a CO2 sensor and, if we do, how should we do it?

Which altimeter to use ?

We have two modules that can compute the altitude: the Yocto-GPS and the Yocto-Altimeter. These two modules determine the altitude with two radically different methods. Lets have a look at the advantages and disadvantages of both.

A USB scale without driver

The Yoctopuce team recently decided to record the weight of each package to be sent, in order to compare the pre-computed weight to the actual weight. And as we don't really like repetitive tasks, we decided to do it automatically. So we bought a few scales with an RS232 output. And this week we take the opportunity to show you in detail how to transform a Kern scale into a Yocto-Scale in a jiffy.

Our blog articles are generally used to give ideas on how to solve issues with Yoctopuce modules.Today, we offer you not an idea but a complete realization, which can be used by any user without computing knowledge...

The Yocto-GPS

By martinm, in New stuff, april 03,2015.

By now, you must have understood it: Yoctopuce R&D department works like a weathercock. The expression is somewhat simplistic, but we do really try to fulfill our customers' expectations. Each time a customer asks us whether we wouldn't want, by any chance, to create a module to do this or that, we carefully write down the request. And we create new products depending on the interest they rouse. This week, it's time for the new GPS module that you have demanded quite often.
