Yeah I think that's right. It's a matter of trading off the water cost savings (and produce quality/yield gains) per plant vs unit cost per device, to determine the optimal density of devices. As I said in the previous comment, right now, high-value crop growers like wine grape growers pay $700-$1000 or more per site (including reader/comms module and sensors), and generally only install one monitoring point per block (I have a system running at one of Australia's top boutique/biodynamic wine makers and at current prices he can only cost-justify having one 10 monitoring sites over his 70 acres of vines). So, whatever we can do to drive down the cost to $20 or less should deliver big wins. > Maybe talk to someone at Nordic Yep, we're working with hardware engineers who are well connected to people at Nordic.
