I’m looking at developing a project that I’d like to use to experiment with using LoRa. It involves making a sound map of the uni campus (UNSW). I’m thinking of a few SparkFun Pro modules with sound sensors? Possible or suggestions please on how best to approach this?
I recommend that you use the Pycom Lopy4 if you want to play around with Lora here in australia: https://core-electronics.com.au/pycom-lopy4.html
Pycom boards are very well supported and there is a ton of documentation available for them. The basic kit to get started is here:
You’ve got great LoRaWAN coverage at the Uni campus already. You could connect this to TTN by following our tutorial and be able to connect almost anywhere in the city for free, without needing to make your own gateway! There is a gateway on campus already!
Let me know if you have any further questions! I can offer as much help as you need to help you get your project off the ground!
Reassuring to know there’s some support out there.
What sound detector would you recommend for the Pycom-lopy4/expansion board?
Like Clinton said, you could use just about any sensor you like. I think this is a good option:
It’s very well documented, and there are lots of examples for use. Keep in mind that this is a 5v sensor, so you will need a level shifter to use it safely with the Lopy4.
