We decided in the [[20161009 Plenum#Buying_more_stuff.3F|Plenum]] to buy a LoRaWAN gateway for the space. However, we don't really know kind of gateway to get. Let's figure out what kinds exist today.

* Kerlink IoT station [http://www.kerlink.fr/en/products/lora-iot-station-2/lora-iot-station-868-mhz] - can you buy that?

==== SDR ====
Just some thoughts. The difficult parts to get seem to be the RF modules for a LoRaWAN gateway. How about building one with a SDR? We have a few badges from the last CCCamp at the space, which work like an HackRF...

LoRaWAN is an RF standard for IoT devices to connect to the internet.

Gateway

See Gateway for more information

Client devices

Research

Available boards:

Test Unit One

  • Arduino Uno
  • Dragino LoRa shield
  • GPS module

Simple Dev Boards

Ideas for Sensors

  • Weather station (Temperature, Humidity, Air Pressure)
  • Water temperature (lake, garden pond)
  • Water level (cistern, garden pond, river)
  • PIR sensor for movement (garage, selfstorage, ...)
    • Also Door openings
  • Offgrid solar monitoring
  • Postbox status -> "You got mail!"
  • Garden/Plant monitoring
  • NOx

Cloud

We connect to The Thingsnetwork

Other Information

Example Sensor projects

Alternative systems

  • Talk about an also LoRa based alternative to LoRaWAN, which should be able to work coexistingly with LoRaWAN: LoraLight
