I didn’t say then. I assume that by unplugging the wind speed meter connector, the error is also eliminated.
Yes, both, I cut/paste your example code . . . which worked perfectly, thnx!!!
Wind was an issue with my prototype, I had a thin, aluminium tube (an old TV antenna) that swayed quite badly. This is a solid stainless steel pole, even when I try to move the pole (which takes some effort) it it doesn’t cause an issue.
I’m thinking I need to experiment with low/high vs high/low interrupt; and/or narrow the window when it detects the transition . . .in a previous life I had access to no end of test equipment, an decent CRO or Network Analyser would be very handy right now . . .
Oh well, trial and error troubleshooting it is.

Hi Kastler, its the rain gauge, not the wind speed ;-)) and yeas the errors stop when disconnected.
I think its electrical noise on the 2m cable from the sensor to the interrupt pin.

Sorry. Try an external pull-up resistor.
i fixed some bugs i found …

Looks very interesting. I want to do something similar. Do you have manual or something?
The circuit diagram and the PCB plans (made in EAGLE) are unfortunately on my laptop that I can’t turn on. But the files needed to build after that are basically here in these topics.
Hi,
Just a question: Why are you using a 100mH coil on the DC output?
100uH was designed for dc converter noise filtering, but not included in the final version.
I inserted the image of such a tiny wifi camera into the blynk as a weather image. For the time being, only on a temporary basis.
UPDATE: Confirmed the noise on the cable . . . it runs very close to 240V light cable in my garage . . . triggered by PIR sensor . . . everytime the light switches on/off there is a random spike in rain value. I’ve tested this by adjusting the sensor time to a few seconds, then deliberating triggering it, this causes a corresponding increase in rainfall . . .
I’ve moved the sensor cables as far away from the power cable, it has helped but still getting RFI . . . I have ordered a shield for the cable . . . ZUJ . . .
