Hi,
A dairy farmer friend asked if I have any ideas about remote monitoring for when he is flood irrigating.
He wants a sensor at the end of the paddock, that triggers when the water reaches it.
He’d like it to cause an el cheapo mobile phone to send a message to his own phone … so he can head off and close the sluice gate.
There are all sorts of systems around, but mostly far more sophisticated and expensive than what he wants to pay ... AUD $2,500
Does anyone have any experience with any reliable, ready made and proven systems … or any ideas for putting one together.
He's not keen on VHF because of terrain, but has respectable phone coverage.
Thank you.
