- measuring interval Sensor.Community and Madavi support only 145 - 150 seconds as measurement interval. So, if you check transmission to Sensor.Community and Madavi the value for "Measuring interval" is set to 145 sec. If you don' t check Sensor.Community and Madavi you can sat it as you like, depending on your needs from 1 sec to 3600 sec.
- LAeq, LAmax and LAmax are the average values ? Yes, it is the Time-Average Sound Level or Equivalent Continuous Sound Level over the choosen measuring interval (again from 1 sec to 3600 sec).
- frequency spectrum
Frequency spectrum values are not supported by Senso.Community an Madavi up to now. The values are shown locally on the webpage but also transmitted to further APIs e.g. to an influxDB (version 1.8). Therefor we also introduced a 2nd measurment interval, which is independent from the Sensor.Community interval. You can set it to a short interval and transmit those values to e.g. influxDB. Grafana can be used for visualizing the data.

Question about the meassuring intreval. Standard it is set to 145sec, but it seems, i cannot make it shorter. Ans also, the time is 145 sec, does this mean that the values LAeq, LAmax and LAmax are the average values over this set time. In this case the average over 145 sec? Furthermore, i like the frequency spectrum values as well and i am looking to retrieve these values and seems that madavi doesnt store them, also no sound data comes vrom madavi? How to retreive all sound data, is there an api to get them from somewhere?
