A Monitoring System for Carbon Dioxide in Honeybee Hives: An Indicator of Colony Health

Sumario:Non-dispersive infra-red (NDIR) detectors have become the dominant method for measuring atmospheric CO(2), which is thought to be an important gas for honeybee colony health. In this work we describe a microcontroller-based system used to collect data from Senserion SCD41 NDIR sensors placed in the crown boards and queen excluders of honeybee colonies. The same sensors also provide relative humidity and temperature data. Several months of data have been recorded from four different hives. The mass change measurements, from hive scales, when foragers leave the hive were compared with the data from the gas sensors. Our data suggest that it is possible to estimate the colony size from the change in measured CO(2), however no such link with the humidity is observed. Data are presented showing the CO(2) decreasing over many weeks as a colony dies.
