I am in the process of designing a system that would send pictures (and some other environmental data such as temperature etc, but that is already working) of ongoing experiments (normally, 8 containers with precisely controlled environment).
For now the cheapest (with correct picture resolution) cmos cams i found are these :
Of course after reading around, i know the arduino is not quite powerful enough to relay a real time video feed, but that is not necessary, since i would only need :
- one picture sent per camera every 30-60 minutes.
- internal memory is not enough to hold even a single image at that resolution so an sd card would be used as a temporary image data “buffer” before the pictures get sent to the pc via serial upon request
- if i got the specs of these cameras right, if i use multiplexers, i should be able to use multiple cameras connected to one arduino ?
- an extra question i also have : this system will need to be connected to the main server for data exchange at all time: for standalone arduinos, are there any other (and cheaper ) methods than using a Ftdi USB to Serial boards?
now i know this is not exactly a simple project (i also heard that there has not been a successful attempt at retrieving higher resolution pictures of that specific camera yet) but does this sound feasible?
First step would , of course be trying out the system with just one camera, at there seem to have been quite a few successfull attempts of doing just that
Thanks in advance!
