Help with a project sending images

[ecabanas]

Hi,

I did a project that sends images to a webservice through 3g dongle.

I used a Raspberry and works perfect, but the problem is the rasp has to be in the middle of a field without energy. I tried to use a solar panel, but the high consumption makes this configuration not viable.

I want to do it with an arduino, anybody has experience doing that? maybe could help to us and making a small budget because is a concept proof and we do not have an enterprise budget.

Thank's

You have conserve power and accumulate energy in combination with large-enough solar panels.

A quick googling:

Yes, rpi is low power but still not battery friendly. Better look at pi zero or even lower power consumption. Then it all depends on how big you can make your project (size of solar panel and battery)

Yes, we could find a pi with low consumption, the problem is how to put the system in sleep mode for example at night...to reduce even more the consumption

Thank's every one

You could just shutdown the rpi and have a timer that cuts the power to the rpi, in the morning the same timer can restore power to the rpi and you are good to go. Then it's up to you how to choose or make the timer

Hi @gohan how did you do a timer? I have no idea how to do it.

Thank's

Maybe look at AI-thinker A6c module that has direct camera interface and sends pictures as MMS over GSM.

[gohan]

I don't know how much MMS cost in your country, but over here they are like 0,5/0,6 € each

Any one knows how it works A6? any example or sketch? I have one but I have no idea how it works.

Thank's again guys
