The data loggers were used in a small scale experiment to record temperature and humidity of air exiting a beehive as part of conservation research.
Dr John Feltwell is a professional
environmental consultant, author, and founder of the
'Wildlife Matters' organisation which furthers the
work of conservation. Wildlife Matters seeks to integrate the
welfare of flora, fauna and habitats into today's countryside
structure, to uphold the conservation of wildlife
through the application of UK, EU and International Law, and to
enhance the environment in all cases.
Dr Feltwell used the Tinytags to monitor the temperature
and humidity of air exiting a beehive in his East Sussex
garden from August 2009 to March 2010. A Tinytag View 2 data logger
with a probe was placed on the metal gauze covering a
hole in the crown board of the honeybee colony. Every 30 minutes,
the logger took temperature and humidity readings from the air
passing through this gap immediately above the honeybee cluster.
Most of the warm and humid air emanating from the bees had to pass
through this hole, so it was an ideal monitoring location.
Key results obtained showed that humidity levels in the
hive were higher (peaking at 97.5% RH) than expected,
based on previous research under laboratory conditions. The higher
humidity levels were probably due to the closed nature of the bee
hive subject to outside weather conditions. The average
temperature in the hive was at least 10°C lower than in similar
By way of a control, a robust outdoor Tinytag Plus 2 data
logger was secured to a nearby fence post at 2m above
the ground. Comparison of the data in and outside the hive provided
some interesting results.
For instance, in October 2009 the minimum temperature in the hive
was close to 30°C yet outside it went down to 3.6°C. Results showed
that the honeybees maintained their temperature several
degrees above the ambient temperature.
This research appears to be the first time that Tinytags have
been used for the measurement of conditions inside bee hives under
field conditions. The results indicate that the temperatures appear
to be lower and relative humidity higher inside the beehive over
the study period than in similar studies under laboratory
