Sorry about that, it should’ve went straight to 3V3 pin right? Keeping C3 connected to the GND.
I don’t understand how “it is not powered with 5V full time” here? What I meant before is that there will not be no constant flow of water, let’s say at max 1-2 hours of constant flow water a day. But now as I see, there is nothing I can do that sensor must be powered all the time at 5V to detect flow, right? It won’t survive on several batteries for long.
From what perspective this way is better? I thought pro mini + lora would be better in terms of power consumption.
ok ill try thanks
