Having already posted about Audio I thought I should introduce myself too.
I develop micro-controller projects as a hobby. It’s a past time away from my job as a computer analyst.
I am not a beekeeper but my neighbour is. He has asked me to assist his group in developing a beehive monitoring system.
Here is the prototype, an ESP32 module based system which measures temperature/humidity and audio samples.
The group is working on breeding native (UK) queen bees which are in a remote location, so remote monitoring will be beneficial.
Future improvements will be adding weight monitoring and LoRa data transmission (the hives are 3Km Line of sight from our base).
Much of this is not new to you guys of course.
