I am looking for some direction for a solution for my farming irrigation issue. I would like to be able to put approx. 5 sensors in the field and when the irrigation water trips a sensor I want it to send a signal (approx 3000’) to a Raspberry Pi. When at least 3 sensors have notified the Raspberry Pi that they have sensed water then the Raspberry Pi will activate a solenoid which will shut off the irrigation engine.
Based on my personal research I am thinking that I could accomplish this with the LoRa network. I am very open to suggestions. Arduino a possibility? Are their individuals that will design a system to suit my needs for a fee? Would it be a very difficult task for a newbie to educate himself and write the code to pull of a project like this? If anyone would be so kind as to point me in the right direction it would be much appreciated!
