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
For some time now, I’m using great RFM12B RF modules to transmit data from my nodes to my gateway and then post data to emoncms. I started to play with Jeelabs library but switched to Felix (lowpowerlab.com) library improvement on.… 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
I’m using day by day a custom board to debug and test my Arduino code. My board exposes an NRF24L01 connector that I’m using also to connect lot of devices (RFM12B, RFM69, MAX18355, SD, FLASH, …) mounted on a breakboard… Continue Reading
Dans un précédent billet je présentais un petit programme que j’avais écrit pour envoyer les informations reçues via la téléinformation vers une base mySQL ou en diffusion sur le réseau. Un autre post détaillait la procédure pour faire fonctionner le… Continue Reading
