In an agricultural area, I'm the owner of an IT company and a family farm where we raise porks and beefs among others. I want to monitor some data in our farm (temperature and humidity of certain location, water pressure/level. Also want to be able to close water valve, schedule lightning, etc.. We already have some camera for gestation and birth monitoring.
I also plan to automate some task in our green house and garden.
All those data/control should be accessible via a computer in the house.
We already have a wi-fi (mikrotik) link beetween house and farm for camera and voip phone, internet/Lan connection but I'm looking for other technology to transmit data from green house and garden.
There is no vegetation in the path.
