Even further away from the gateways, RSSI -73, SNR 14. There will be no problem with measuring the level of water in a ditch nearby. Those #Dragino sensors work pretty well at first glance, but they were not made for wild areas – still haven't found a way to switch off the very bright LEDs that light up during transmission. We want to kep this place dark at night. And the LEDs use up the battery.
Oops – not sensors – gateways. My instance still doesn't support editing. I might have to move.
The barrel was easy – just a few metres away from both the sensors. The question was how would the sensors transmit through thick, wet vegetation. I'm not measuring anything but radio parameters from this spot on the edge of a #wetland meadow in #Polesia.
