I am working on a project where I have to wirelessly turn on and off Electric motor pump, which is at a distance of approximately 500 meter from my home. I need help to select the wireless communication so that I can send data from my home either to turn off or on the motor. Also is it possible to connect my micro-controller to the internet of cellular network wirelessly(Without a GSM module)

  • \$\begingroup\$ You could use a RockBlock Iridium satellite module, but that's hugely overkill. \$\endgroup\$ – skillz21 Mar 4 '18 at 5:59
  • \$\begingroup\$ Wait, are you asking for a suitable point to point connection? In that case, you might be able to use a HC-12, but that largely depends on any obstructions in the way. \$\endgroup\$ – skillz21 Mar 4 '18 at 6:05
