A simple Python module for reading Onset HOBO data logger data
License: Other
Python package for working with HOBO temperature and RH data logger data. At this time it supports HOBOware and HOBOmobile CSV exports from Onset models: * HOBO Pro v2 U23-001, U23-002 * HOBO Pro H08-030-08, H08-032-08 * HOBO MX2301, MX2302 It may or may not handle data from other HOBO loggers, though HOBOware should produce a compatible CSV format for other similar hardware. The data is assumed to have a timestamp field and a temperature field; fields for relative humidity and battery are supported when present. Data exported from the discontinued BoxCar Pro software is not yet supported, nor is highly customized HOBOware .CSV output. Example usage: from hobo import HoboCSVReader with HoboCSVReader('my_hobo_data.csv') as reader: print('Reading %s ...' % reader.fname) print('Serial Number: %s Title: %s' % (reader.sn, reader.title)) for timestamp, temperature, rh, battery in reader: print('%s %03.1f F %02.1f %% %.1f V' % (timestamp, temperature, rh, battery)) >>> Reading my_hobo_data.cvs ... >>> Serial Number: 10173910 Title: My Hobo Data" >>> 2017-01-13 01:00:00-08:00 31.4 F 79.6 % 3.5 V >>> 2017-01-13 02:00:00-08:00 31.4 F 78.9 % 3.5 V >>> 2017-01-13 03:00:00-08:00 31.4 F 77.9 % 3.5 V >>> 2017-01-13 04:00:00-08:00 31.3 F 77.2 % 3.5 V License: As a work of the United States Government, this project is in the public domain within the United States. 2016-02-24 David A.

Here's an ancient HOBO Pro H08 data file (originally .dtf format) exported from modern HOBOware, demonstrating RH% values > 100.0:
"Plot Title: Secret Cave"
"#","Date Time, GMT-07:00","H08 Temp., °F (LGR S/N: 274341)","GCap. RH, % (LGR S/N: 274341)"

Current release of hobo-py
fails to detect its temperature column.

Hello! I was delighted to see this project! Does it work for Raspberry Pi? The Pi recognizes the HOBO Base Station that I have but I am stumped on next steps to get the Hobo to download data to the Pi. Any thoughts? Thank you very much!
The old BoxCar Pro software produced a more limited CSV output than does HOBOWare. Consider adding seamless support for these files (which were likely produced in the old "hockey puck" H08 days).
I don't have access to BoxCar Pro anymore, but it looks like this may be an example of its default output with a HOBO H08:
Date Time Temperature (*C) c:1 High-Res Temp (*C) c:1 2 RH (%) c:3
