A Banana Pro Weather Logger

weather-logger.conf; keep track of variables.


I prefer to keep variables that may be used in more than one place or script in a configuration file. There isn't much in my weather-logger.conf file right now but I will be adding more when I get around to setting up the data server and web page.

# To adjust air pressure at weather logger site to air 
# pressure at sea level (MSL hPa) the elevation of the
# site is required. The elevation is then  divided by 
# 9.2 (hpa per metre) The quotient is then added to the
# local air pressure obtain MSL hpa, e.g. 95/9.2=10.326
PRSSR_ADJST=10.326
#
# Amount of rain water per rain guage bucket tip:
# The rain guage catchment area is 6503.88sqmm. If 1mm of
# rain falls on rain gauge, the volume of rain would be 
# 6503.88 * 1mm, or 6503.88cmm. 45cc of water from a syringe
# tips the rain gauge bucket. 45cc=4500cmm each bucket tip.
# Therefore 4500 / 6503.88 = % as mm of rain per bucket tip,
# or 4500 / 6503.88 = 0.6918946844, say 0.7 (70%)
RPT=.7 # mm. rain per (bucket) tip
#
# Path to temporary tip count file
TIP_COUNT=/tmp/tip-count
#
# Path to temporary file containing the most recent
# line of of weather data output from get_w_data
TEMP_DATA=/tmp/temp-w-data.csv
#
# Path to weather-data.csv
DATA_CSV=/var/lib/weather-data/weather-data.csv
