Transmitting sound and image over a LoRa link #LoRa #Radio


loracamera allows transmission of sound and images over a 915MHz LoRa link to a base station near a WiFi connection. Currently it is set up to a send a frame from a serial TTL camera and a few seconds of sound from a microphone, but it can be adapted for most data using LoRa directly.

I’m using two of the Heltec WiFi LoRa 32 v2, readily available on amazon etc. I’m able to get about 1km in range in a dense wooded place from this setup.

The camera I’m using is this one from Adafruit, but I’m looking for better options. The library is very fiddly, I had to slow down a bunch of serial calls to get it going on an ESP32, and the camera quality is low.

I’m using this Adafruit MEMS i2s microphone as well.

See GitHub for more details.
