Load-Cell Center-of-Mass Localization for Non-Invasive Beehive Monitoring

A non-invasive IoT system that locates a bee colony inside a hive and tracks its honey consumption from four corner load cells. Treating each load cell's force reading as a point mass, the colony's planar position is the center of mass of the four readings, while the falling total weight measures honey use. Digitized by HX711 ADCs on a Raspberry Pi Pico and relayed over Wi-Fi via MQTT to a Raspberry Pi that logs to MySQL; a physical bench model validated the reconstructed trajectory.

Automated monitoring of bee colony movement in the hive during winter season Rostyslav Koroliuk1,†

An inexpensive, non-invasive system for monitoring a bee colony inside a hive during winter, when opening the hive would stress the bees. Four load cells at the corners of a platform beneath the hive…
