I need to evaluate if Arduino eco-system could be a way to log sensors and transmit that onto our server via gprs.
Who could help us in such evaluation, is there some volunteers or consultants we could discuss with ?
the main idea of our project is the have a unit that log sensors, transmit data onto our server
can upgrade its configuration remotely (including firmware)
Sensors are high quality sensors from the market : hygroclip from rotronic for the temp and RH, kipp&zonen for radiation, young for wind, watermarks from irrometer for soil humidity, decagon sensors,...
Transmission, we want to give the choice to our client : gprs (if no LAN), ethernet, wifi otherwise. Is it possible to offer it as an option and pick the appropriate shield ? Can the firmware manage an automated recognition of the shield plugged and us it to transmit data onto our server ?
Remote sensors : we also thing about sensors in the field (like watermark humidity probes) but cable are not welcomed in such environment. Can we use Xbee to communicate between main unit ant such sensors. Do we need an arduino board per sensor or does the Xbee have enough 'intelligence' to deal directly with the main unit ?
We also care about memory issues and data losses (if the network fails for a while). Any comment on this ? do we need an extra shield ?
We also care about electric consumption (is the arduino efficient on this point ?) has anybody realized projects far from it computer, with battery (and solar panels) ?
Please provide as much details as you can about the sensors
TYPE, NUMBER, WORKING RANGE, ACCURACY, FREQUENCY, LOCAL/ REMOTE, DATASHEET
Build a 2 stage system,
I am currently working on the 'functionnal specs listing', I will be able to give you a recapitulating table soon. But for some sensors, no definitive choice has been done and we remain open to anything that will 'do the job'.
I am not sure to understand what you mean by frequency : are you talking about the signal itself or are you talking about sampling / recording frequency ?
Build a 2 stage system,Do you mean : creating our own design based on arduino ?
