Hi there,
For my final year engineering project im developing an environmental sensor network andXbee appears to be just what I need since I want to use an RF mesh. However Xbee 2 or Xbee 3? Im going to be using an arduino micrcontroller in each node to take sensor inputs as even though Xbee 3 can receive and process the inputs, this is because each node will have an SD card to save readings to. Im also looking at what is easier to setup to get the mesh working (limited time in the semester and studying part time) Xbee 3 can use Digimesh which i understand is more straightforward to configure the mesh with rather than Zigbee mesh.
