Running My LoRa System Across A Field For Real World Experience


LoRa at Tom Sawyer Park Distance Test went well.



I'm currently working on building a sender and a receiver LoRa signal across a large area or field.

This experiment or chance to experience my first LoRa system has been in the making for quite sometime. I've been trying to accomplish this with pre-built ESP32 devices, but it just haven't worked out, especially since one of the devices was hooked up wrong, my mistake, and caused virtually a smokey failure. You know, the electrical discharge of a burnt chip. It only took a second before realizing that it's a gonna.

Even before that, I've been a bit intimidated by the controller device. But, as I've tackled more and more electronics throughout my years, I'm starting to understand them a lot more. I've becoming familiar with how they are supposed to be working. I did it the hard way. Trial and error and a lot of personal researching and self-teaching.



LoRa across Tom Sawyer Park

The first test was too close and didn't really give me a distance to see if the LoRa devices can do what it can do. So I took the devices out to Tom Sawyer Park where I know of a place I can really grow some space between the devices.

The Rayex devices didn't disappoint. They did exactly as advertised. I actually ran out of real estate when I was moving across the field. I simply couldn't go any further and when I looked at the screen, the receiver was still being updated from the sender.

It was if they were really just next to each other with no drop in packets. I'm amazed at how such a small device can send its signal this far.

To the experts at this, they're not impressed. But I've never seen anything like that.

The many applications this can used for.

  • for taking a picture across a rural area.
  • activating a push button from the house to across a field.
  • of course, alerting someone of motion from across a large field.
  • monitor movements at large concert, wedding or sporting events.
  • At as a gateway between to different separate networks. A network of wifi devices limited in space, suddenly has gotten larger when using LoRa devices as gateways to their repective local WiFi networks. Think about it.

Of course, a gsm modem on an ESP32 device can be limitless, but if you pare these devices with a gateway running off of solar panels, maybe you can create a wide area surveillance system closed off from the outside world.
