Today we were introduced to XBee’s which are wireless RF modules that have a of 1km (for what we are using) but you can get ones with a range of 80km!!! This range alone impressed us all, and the thing is they can intelligently create their own mesh networks, so you can use 5 XBee's to have it broadcasting from 5km away. Crazy impressive.
So then we were told about these things… Ecoid’s
Ecoid’s consist of a XBee, battery and the desired sensors in an enclosure to seal from the elements that you can place into the environment to transmit data back to you in a relatively simple way. The Ecoid’s that the iDAT leaders have created use a variety of sensors that can relay almost any information you would like (GPS, RFID, Light, Humidity, Temperature, Stretch) and send it back to its partnered XBee connected to either an Arduino or computer to process the data. You can also access the data from an RSS is you want to visualise it, here is the RSS for Ecoid 1…
As you can see (you may need to view>source) its location is shown in the gps, and it shows the data, light, humidity, temp and stretch (which is calculated by the stretch in the black cable they hang them from - see image).
We’ve been asked to make visualisations for the data from any of the Ecoids, so time to get thinking.
