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 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 laboratory-based research.
By way of a control a Tinytag Plus 2 logger
was secured to a nearby fence post at 2m above the ground.
Comparison of the data in and outside the hive provided some
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
