The anemometer's signal is expected to be under 2V. If this is true, the ADS gain might be able to be set for higher precision. Also, it may be useful to test that the voltage to windspeed mapping in sensorlogger.ino is correct, though I'm not sure of a good way to calibrate that.

The current voltage to windspeed mapping definitely seems off. It seems to report windspeeds much lower than expected, but I don't know by how much. Current mapping is based on the data from adafruit's product page. It should be confirmed that this mapping is implemented correctly, and if so, devise a way to calibrate the sensor better.
