- It reports every 5 seconds.

- This station is located on the 2500 block of Alvin Street.
A third station, https://www.wunderground.com/personal-weather-station/dashboard?ID=KCAMOUNT141, is located on a Google X building on Mayfield Ave.
All stations on wunderground.com provide graphs that you can move your mouse over to see values at any given time of day, and you can also ask for weekly and monthly graphs.
Be aware that weather stations do not all provide the same data, and/or the same quality of data. This is a function of the quality and type of actual sensors used, as well as the correct placement of these sensors. Calibration is also a factor. Most amateurs are not able to locate the sensors in the location prescribed by the NWS, and thus measurements of wind speed and direction, for example, are subject to inaccuracy due to nearby buildings, tall trees, etc. On the other hand, all this data is free for all to use, so be aware that the stations listed above have their challenges and are providing data on a best-effort basis.
