Can you see the #LoRaWAN distance sensor that will, once properly mounted, measure the depth of water in a ditch on our border, in the #wetlands of #Polesia? I hope potential thieves won't see it either.
Once it's properly mounted and calibrated it will send data once every hour or so to preserve the battery, but now it takes measurements every few minutes. Once in a while the distance drops by some thirty centimetres, I wonder if this is the cause.
