Smart Hive Monitoring: from sensors to signal.

A low-cost monitoring workflow designed around the realities of moisture, power, connectivity, propolis, and the need to turn readings into decisions.

Lab-clean data rarely survives the field.

Commercial hive systems can be expensive and rigid. DIY systems can fail under moisture, power loss, signal blockage, and noisy sensor output. The project’s goal was not to collect the most data; it was to produce reliable signals that could support less invasive hive stewardship.

Technical implementation inside an active field context.

Ayotunde’s public portfolio describes hands-on support across low-cost sensors, cameras, installations, data logging, and monitoring workflows for Capitol Bee Care. The case report documents the system architecture, field-hardening decisions, pipeline, and reported pilot outcomes. It does not claim that one person independently produced every component or field result.

Technical contribution

Sensor and camera deployment support, environmental data integration, monitoring workflow design, field troubleshooting, and technical documentation.

Domain collaboration

Placement, intervention thresholds, and reliability decisions were informed by beekeeping practice and real deployment constraints.

Every component had to earn its place.

Filter at the edge. Interpret in context.

Level 1

Edge filtering

The ESP32 takes sequential readings and uses the median to reduce transient spikes from brief disturbances.

Level 2

Transmission

The device wakes on an interval, connects, transmits a processed packet, and returns to low-power operation.

Level 3

Trend analysis

Temperature and humidity are evaluated over time so normal daily fluctuation is not confused with an intervention signal.

Decision layer

Health classification

Conditions are translated into stable, stress, or critical states with a corresponding beekeeper action.

Reliability emerged from the system as a whole.

Placement

Sensors were positioned near the brood-box thermal core while avoiding the entrance, airflow blockage, and colony disruption.

Power

Sampling intervals and deep-sleep behavior were used to extend feasible deployment time between maintenance visits.

Moisture

Coating, sealing, and an IP67 enclosure addressed corrosion and water ingress.

Signal

External antenna placement and filtered readings addressed hive-material interference and transient noise.

Useful signals with explicit source labels.

Evidence standard: the portfolio no longer presents the report’s cost, uptime, inspection, or survival figures without identifying the project report as their source.

A monitoring concept, not a finished commercial product.

  • The portfolio does not include a public raw pilot dataset or independent validation study.
  • Thresholds may need adjustment for colony, season, climate, and sensor placement.
  • Connectivity and long-term enclosure performance require broader deployment testing.
  • Future work in the report includes solar autonomy, LoRaWAN, acoustic sensing, and a simplified mobile dashboard.
