Estimated increase in data volume with addition of node-based project

Stations
1

Hi all,

I have a motus station (sensorstation) at a site that has been collecting data of migrants passing through and sometimes stopping briefly at the site. So not a huge amount of data, but not nothing. The station is connected to the host’s internet via ethernet.

I will be starting a new project at the site this spring that involves setting up 10 CTT nodes and tagging 20 local breeding birds (434 MHz). The data will transfer back to the existing sensorstation at the site. The host is wondering how much additional data will be transferred over their internet with the addition of this project. Does anyone have a rough estimate from their own experience? Of course it depends on a lot of factors, but even a ballpark estimate would be helpful.

@user80, would CTT happen to have an idea?

Thanks!

Amie

Hi Amie-

It will be minimal- perhaps a GB or two per year, but more likely less than that.

Cheers,

David

Thanks David! I found the bit in the node manual that said 27,000,000 records = 1 GB of data and calculated the following, which I would consider to be likely way more detections than will occur in reality:

30 hits/min (given a LifeTag 2 sec burst interval) x 60 min/hr x 18 hr/day (study happening near the summer solstice in Canada, so long days for LifeTags to transmit) x 30 days/month x 3 nodes (likely the max # that would detect a tag simultaneously given distances apart) x 20 tags = 58,320,000 records = 2.16 GB/month.

I don’t expect to actually get this many detections, but wanted to give the host an overestimate of how much data would transfer over their internet rather than an underestimate. Luckily, they were fine with this amount!
