When designing the wearable device, we need to make some functional decisions, namelywhere to wear the devicehow to power the device (how many batteries? with which capacity?)how to keep costs down Let' start from the most important topic: where...
Since my last blog, I have tried a lot of things, with the sensors I already had. The original plan was to integrate the newer MAX30102 and replace the MAX30100 with it to measure SPO2, HRV and HR more accurately. I was a bit surprised when the ...
In the first post, I shared an overview of the different options of the Connection Unit I'm looking to build over time. For now, I want to start with the simplest version, which is supposed to connect a solar system to a grid of (roughly) similar...

This post is for those with problems with its Wifi module.If your Arduino Nano 33 IoTArduino Nano 33 IoT works but when trying to access the wifi module it does not respond, you may have to update the firmware. In this blog we tell you how we did it ...
This week we have tried that our sensor measures the opening of the window using only the accelerometer, without using the magnetic linear encoder that we have used in the previous blog.The measurement is carried out by making a double integration of...
This was not a planned blog post, but I bricked the Arduino Nano and may be my experience could be useful to anyone else who may have the same kind of problem in the future What happenedWhile testing low-power modes, I created an application tha...
Reasons for the projectThe number of elderly people living alone has been continuously growing worldwide. This independence comes with the risk of not receiving prompt attention if an accident occurs. According to <>, a third of the people over...
