I'd buy it outright were it a bit less pricey.</p>

As far as I can tell I could use the output of this sensor to calculate the gravity of wort while fermenting. Any beer nerds out there with some ideas?</p></p>

I skimmed through the datasheet, but I only saw a resolution on the conductivity reading. How does this translate to TDS? I need to measure really small changes, ideally less than 0.05%.</p>

Thanks SparkFun!<p>http://water.usgs.gov/owq/FieldManual/Chapter6/Final508Chapter6.3.pdf</p><p>How cool would it be if citizen water quality monitoring got the sort of traction that all those DIY Geiger-counters got after Fukushima! Brine from oil and gas production getting into your water well? Measure it directly - put a number on it! Salinity in the creek too high for cut-throat trout? Put a number on it!</p></p>

As long as the voltage swing is about 3V or greater, 0-Vcc levels will be detected by the hardware.</p>

If you connected this to a proper RS-232 port, it would not work. Please correct this in the spec as it is misleading and some people would take it to mean you can connect it to a PC or something similar directly.<p>RS-232 specifies that the voltage must swing between a negative voltage and a positive voltage to represent logical 0’s and 1’s. The minimum swing normally accepted for this is from -5V to +5v with anything in between being ignored (i.e. 0V).</p></p>

I see Atlas-Scientific has different probes for this (K=0.1, K=1 & K=10) and you folks carry the K=1. I am interested in this for a marine aquarium setup though so the K=10 is what I need...</p>
