Number vs voltage recording data set for Schumann's resonance analysis at 250 samples per second
In this study background environmental Schumann's resonance was recorded utilizing a portable coil antenna and detection circuit. The detection circuit was battery powered and enclosed in a metal box. 19mm PVC pipe and fittings were used to build a regular octagonal antenna frame with side length of 40cm. The coil antenna was oriented east to west and located at 10.66457701467502 degrees north latitude, 61.11573950258856 degrees west longitude in the northern range of Trinidad away from the 60Hz national electricity grid. 50 independent 35-minute data sets were obtained during the local time period of 09:30 AM to 6:30 PM on different days between the dates 20th February 2022 and 11th May 2022. These data sets were utilized to derive estimates of the first 4 Shumann's resonance frequency peaks. In addition, the input to the Schumann's resonance detection circuit used in this study was connected to ground and the corresponding noise output was recorded for 35 minutes at a sample frequency of 250 samples per second. This noise file is also included. The data files are labeled R1 to R50. A folder-note file is also included indicating the date that each data file was recorded.
