I'd like to make a WSN for a university project, well the main focus will be to visualise in a creative/interactive way various environmental parameters. So ideally I would like to place env sensors in various places of my university (indoor and outdoor). I was thinking aorund 30 different locations to make the project interesting. THe problem is to keep the budget very low and the timeline is of 2 months. Do you think is that feasible? What solutions would be available? I've seen Squidbee is no longer available...is there maybe a cheaper way to use a similar technology? Can you maybe advise what should I look for?
