Hi i need to measure rain and wind. But together this sketch

no working only measure rain and wind no. But why? I tryed change pins but unsuccessful.
… Thanks…

This is your third topic on this project :thinking: mostly us troubleshooting your bad code or wiring… no real Blynk relevant issues.

What have you tried on your end for troubleshooting your latest issue?

You have no interrupt attached to your “hallPin”, so no matter how many pulses the anemometer is sending to your board, the code won’t do anything with them.

As I said before, you’ll need to manage your interrupt priority very carefully.
Pulses from your rain gauge will come much less frequently than from your anemometer. Missing one or two anemometer pulses is no big deal when its lashing it down with rain and blowing a gale, but a missed rain gauge pulse will make a significant difference to your stats. If you don’t believe me then put your weather station outside when its raining and see how frequent the wind pulses are compared to the rain pulses.

With two sources of interrupts then you’re probably going to have to use detachInterrupt() for the anemometer while you’re processing then rain gauge interrupt, then re-attach it again afterwards. This will ensure that your range gauge data is processed without being interrupted (see what I did there :stuck_out_tongue_winking_eye:) by a pulse from your anemometer.
The processing time of the void rain() function may seem insignificant at the moment, but when do finally realise that you wan’t to do more with this data than your current reset to zero at midnight then the processing time will increase.
Once you start to add-in wind direction, pressure, humidity and temperature readings then it becomes even more important to have your code well structured and your interrupts managed properly.

However, you seem to have ignored every piece of coding advice I’ve given you so far with this project so we’ll see what you do with this bit of guidance.

Pete.

Sorry but my latest problem is solved: problem was in bad used pin.
Now i founded new issues because i was think it is clearer and it is different problem…

Thanks. But i dont know how i am no good coder. So i used two ESP8266 devkit. One for anemometer and SI7021 and twice for rain guage. It is working. Only i dont know for start measurement wind i always have to click on the serial monitor in Arduino 1.6.5? Thanks.
