By Blog Guest, in Misc, november 27,2020.

This week, we have invited a guest on our blog. Infinitus is one of our longstanding customers. They manufacture outdoor displays, and as you might guess, they have some use for Yoctopuce's light sensors. The Infinitus team wrote the article below and asked if we could publish it, we accepted.

By mvuilleu, in Programming, november 20,2020.

JavaScript is a language that doesn't stop evolving under the influence of web application developers. Moreover, the will to reuse components from one project to another and to ease the creation of web interfaces lead to the emergence of numerous systems of modules, of packaging, and of interface design frameworks.

Someone recently asked us how to interface an AMS TSL2591 ambient light sensor with the Yocto-I2C. It's an interesting question for two reasons: the TSL2591 is considerably more sensitive in low light than the Yocto-Light-V2 or the Yocto-Light-V3 and more particularly its I2C protocol is not the simplest to implement. It's an opportunity to test the limits of the Yocto-I2C autonomous job system.

How to correctly measure ambient temperature

By mvuilleu, in Measures, november 06,2020.

Everyone knows that any measurement tends to disturb the physical quantity we are trying to measure. This issue is particularly blatant when you try to measure the temperature with a USB sensor. Some sensor types affect the temperature more than others, but there are ways to limit the problem. Let's look at this in more details...
