Each hive has an array of electronic probes and chemical probes. Bidirectional entrance counters monitor the coming and going of every bee.
Pressure transducers track changes in hive weight.
Traps that empty into clock-driven trays document the pollen gathering activities of the bees. Sensors follow the ability of the bees to stabilize temperature and humidity conditions in the brood nest. Garon Smith , the project's chemist, inspecting his air pumps. Volatile chemicals are sampled by pumping air through small glass columns packed with graphitized carbon and two different molecular sieve materials. The columns are attached by brass ferrules to small copper tubes inserted into the pollen trap, entrance vestibule, brood nest, and honey storage boxes of the hive.
