So, this only appends the data to a csv file, but there are no plots and no aggregations? This is very disappointing, as there is already a mature and open source solution: thingspeak.
I personally use rrdtool for this kind of data.

the noise immunity of this circuit is laughable at best. hooking it to vcc/gnd of an avr and letting the avr switch ~50mA (led a led bargraph) will trigger the gate led. operation depenend on input voltage. this is another badly designed circuit.

You left D13 unused and attached LED13 to D14?
Very, very idiotic.
Attaching D13 to the LED would have the added benefit of having a solder point to use that otherwise unreachable pin. Not to mention that all arduino boards traditionally had the LED on D13.
Well… it’s been more than two years and nothing changed about this badly designed module. As usual i will vote with my wallet and buy Adafruit or Pololu modules instead.

Even David (EEEV Blog) is selling his because of this (idiotic!) limitation.
