This is an autonomous weather station based on an Arduino mini. It sends 4 times a hour the values of the sensors (humidity, temperature and atmospheric pressure) to a server with WiFi.
If the device is activate, you can see the weather on meteo.yanonix.fr
Bad endurance (2 weeks).
Right now, the Arduino is used in another project.
The device uses 3 batteries AA. The autonomous is around 2 weeks. I tried to reduce the energetic consumption while it is in the sleep mode. I should remove the power diode. Getting a sample each 15 minutes is probably too mutch. I should add a solar panel to extend the batteries or become energetically self-sufficient.
I move frequently and each time, I don't find the right spot to place my weather station. It needs to be in the shade and far from walls.
