Beehive health monitoring

The problem

A beekeeper can't open the hive every day, because opening it disturbs the bees. So a dead queen or a parasite infestation is only discovered weeks later, when it's too late to save the hive.

How it works

1. MountingThe load cell goes under the hive, and the sensor box and microphone are mounted on top in an IP65 enclosure.
2. MeasurementTemperature, humidity, and weight are measured at regular intervals, powered by a solar panel and battery.
3. Sound analysisThe microphone records short clips of the buzzing, and frequency analysis reveals changes linked to losing the queen or swarming.
4. WeightThe change in weight shows honey production, and any sudden drop points to swarming or theft.
5. UploadReadings are uploaded when a connection is available and stored locally until it returns.
6. AlertsThe beekeeper gets an alert when any reading leaves the normal range, with a full log of the hive.

Project features

• Very rare — it isn't done in the region, which makes the project stand out.
• It combines IoT, sound analysis, and machine learning in one project.
• A real agricultural application with an existing market.
• The weight reveals honey production without opening the hive.

Expected challenges

These are the main obstacles to expect during the build, laid out clearly so you know them before you start.

• Sensors inside the hive are exposed to moisture, wax, and propolis, so the enclosure is essential.
• Analyzing the buzzing requires recorded data from healthy hives and from hives with problems.
• The load cell is affected by heat and wind, which requires filtering and calibration.
• Power: the solar panel and battery must last through cloudy days.
• Apiaries are usually out of Wi-Fi range, which requires local storage or a long-range connection.

The consultation gives you a solution for each one.

Expected committee questions

Prepare your answers in advance: these questions come up often in defenses of similar projects.

1. How does the system analyze the buzzing, and which frequencies indicate a problem?
2. How are the sensors protected from the bees and moisture inside the hive?
3. The unit runs on solar power — how were the panel and battery sized?
4. What change in weight indicates the bees leaving or honey being stolen?
