Overview

Built an ESP32-based IoT monitoring system for beehive health analysis by combining environmental, weight, and acoustic sensors. Developed an MFCC-based audio classification pipeline to analyze bee sounds and support lightweight edge inference.

Problem

Beehive health can be affected by changes in environmental conditions, colony activity, and acoustic behavior. Continuous monitoring across multiple sensor modalities can provide useful signals for detecting changes in hive conditions without relying entirely on manual inspection.
