LongHive

A beehive monitoring system based on the Helium Developer Kit and a RasPi with Seed’s 2-Mics ReSpeaker PiHat for audio acquisition and basic audio analysis with classification of queenless vs. with queen. Telemetry is done via the Helium network (it’s based on LoRaWAN).

Project description

Source Code

Audio analysis

Audio analysis was realized a bit cumbersome: First convert audio to a graphical representation, in this case a spectrogram, then analyse this graphics with deep learning, in this project a pre-trained Tensorflow Lite Interpreter.

Sensors

Beside weight and temperature they measured CO2 and air quality . Unfortunately they used the worst weight sensor you can get, the unreliable bathroom sensors:

LongHive won 2 500 $ and some stuff (hardware, data plan) from the sponsore Helium on contest from hackster.io. Congratz!
