I'm trying to build makeshift seismograph-type devices. My goal was to leave a few along a nearby fault line area here in California, and have the readings sent to my laptop from each unit. Thing is, there is no cell reception where I want to set these up, and so a direct connection with my pc is the way to go...and while things are happening, I'll be parked a few hundred feet away. According to Google, a 2.4 GHz connection theoretically has about a 300ft range outdoors.
I ordered a few Adafruit Feather M0s ([login to view URL]), attached mini-coaxial FXP74 2.4GHz band antennas ([login to view URL]), and connected Adafruit ADXL345 digital accelerometers ([login to view URL]). I was also gifted a Piezoelectric advanced accelerometer that I would like to setup and use as well. I'm assuming I'll need another component acting as a "server" between the 2-3 units and my pc? Is this doable, or am I forced to pull data, one at a time?
I bit off a bit more than I can chew, and the tutorials are confusing me more and more. I've included a picture of my breakout board. Please, reach out to me with any follow-up questions.
