What the software does
What the Software Does

  • At prespecified intervals, crontab:

    • Runs shell and perl scripts to capture hive data

    • Updates graphs

    • Emails computer status and daily graph

    • Backs up data and store offsite

  • Web pages updated in real time and served to the world

Update long graphs

Example cleansing or orientation flight
Example: Cleansing or Orientation Flight

  • At around noon on two days (12/27/13, 1/7/14), a sudden drop in hive weigh was noticed

  • From a 0.2 lb drop (62.7 – 62.5), a rough estimate of the number of bees leaving can be calculated; assuming 3000 bees per pound, approximately 600 more bees were flying

  • Is it possible to calculate hive strength and egg laying ability of the queen?

2014/03/30 14:20 + 104.9 lb

2014/03/30 14:25 + 105.0 lb



Example dehydration and respiration in high humidity
Example: Dehydration and Respiration in High Humidity

  • From midnight- 8 AM the hive gained weight (~0.2 lb = 3 oz = 90 mL)

  • Source is probably fog and/or condensation from bee respiration due to lowered dewpoint

Example untreated varroa infestation
Example: Untreated Varroa Infestation

  • Total hive weight is dropping

  • Treated with half dose MAQS on Sep 15, and Nov 10 – ineffective

Audio sampling
Audio Sampling

  • Microphone placed in center of broodnest

  • Frequency range: 100–16000 Hz

  • Sound sampled at 16k Hz for 10 sec, every 2h from 7am-7pm (depending on season)

  • 1000 Hz lowpass filter to reduce noise

  • Spectrogram updated q 2h on day’s events

  • Ogg format used to archive sounds

Audio spectrogram
Audio Spectrogram

  • “Looking for” queen tooting/piping (350-550 Hz = G sharp), quacking (200-350 Hz), regular buzzing, disturbed sounds, tapping feet

What i ve learned
What I’ve Learned

  • Bees are incredible creatures

  • Awesome insight can be obtained by simply weighing the hive

  • This can be done cheaply

  • Daily activity varies dramatically per nectar, pollen, weather

  • I’m more in touch with my bees, but inside the hive less

  • We need more hive monitoring! Join me!

Next steps
Next Steps

  • Real-time audio streaming and analysis, email alerting for weight changes (swarming)

  • Video quantification of traffic?

  • Autonomous hive computer:

    • Raspberry Pi B: solar, wifi


Example spring nectar flow ga003
Example: Spring Nectar Flow (GA003)

  • Adding and removing honey supers is best managed by knowing the beginning and end of nectar flows

  • This hive experienced a 90 pound weight gain in just three weeks

Example: Untreated Varroa Infestation
