Today I would like to introduce a new breakout board to read temperature values from the most used sensors in the industry such as PT100 and PT1000 (well at least in France). Why this board ? It’s not the first… Continue Reading
After several articles and some intensive tests with ULPNode, it’s now time to explain how the low power engine has been built. Even if you can find plenty of Arduino clone node, when it’s time to power them with battery… Continue Reading
Août 2016 : Depuis l’écriture de cet article beaucoup de choses ont changées en ce qui concerne la téléinfo, que ce soit le matériel ou les articles. Alors pour des informations “up to date” (nouveaux articles et produits) concernant la… Continue Reading
Today I wanted to do a quick project status of the 1st prototype of ULPNode I received some days ago. After the introduction of ULPNode, and both articles about bootloader (1 and 2) used, for this one I will start with… Continue Reading
Following the 1st part of bootloader description for ULPNode this article describe what modification have been done to optiboot to be able to drive new Ultra Low Power nodes. Optiboot For this, I started from original optiboot (latest trunk from google code)… Continue Reading
Following the previous article presenting the ULPNode it’s now time to deep into the technique used to setup the starting mechanism of ULPNode bootloader. In this 1st part I’m introducing the goals to achieve and in the 2nd how it has… Continue Reading
Why this new project ? For some time being, I researching a way to have to have a kind of “universal” Arduino node sensor. When I say universal, I’m talking about connecting to it several sensors type (Temperature, Humidity, Lux,… Continue Reading
Playing around with Hoperf RFM12B and RFM69 for my wireless sensors, I discovered they also have one interesting sensor for temperature and humidity called TH02. Just look the picture below, this sensor is so small
