Smart Hive Monitoring: What IoT Sensors Can and Cannot Tell You (2D)

This 2D companion strips the beehive down to a plain side-on cross-section so the sensor-vs-reality lesson reads clearly: a weight-scale readout, a brood thermometer and an acoustic sensor each report one number continuously, a dropdown swaps between five ground-truth colony conditions (healthy, queenless, a varroa outbreak, a strong nectar flow, and a pre-swarm colony), and pulling the brood frame out for a manual inspection reveals — in plain text over the comb — exactly which conditions those three cheap sensors could never have caught on their own.
