5.1. Contact thermosensors
There is a great variety of contact thermosensors available. For the measurement of ambient temperature, sensor size is not so critical, though smaller sensors react much faster to changes in ambient temperature than larger ones. For honey bee body temperature measurement, however, it is indispensable that they are not just small but tiny! Otherwise, large measurement errors are to be expected. Furthermore, for measurement of brood nest (comb) temperature, care has to be taken to place the thermosensors in the correct (desired) position, e.g. in the actual centre of the brood comb.
