Hi- I am an oceanographer and I study the drift of icebergs and their interactions with the ocean around them. I use very simple GPS trackers but they only transmit position and time. I am building a new ice tracker with external sensors. I want to use the 4" enclosure with a 5 hole aluminum end cap. The temperature and pressure sensors look great. Any ideas on where to get an affordable, but somewhat decent, and easy-to-integrate conductivity sensor? So far, I am looking at the atlas kit: http://www.atlas-scientific.com/product_pages/kits/ec_k1_0_kit.html . Any others out there?
I will use the rockblock mk2 to transmit data. http://www.rock7mobile.com/products-rockblock
I’ll post updates as I build. Any suggestions welcome!!
