About the Secondary development:
Wind speed is passive switch quantity, wind speed sensor, turn 1 turns, 2 pulse =2HZ.
Formula for wind speed: m/s=wind speed Hz * 0.34
Rainfall is passive switch, rain bucket reverses once =0.33mm
Wind direction: resistance network, equivalent to stepping potentiometer, the user connected to a 10K pull-up resistance voltage, SCM AD can detect the voltage.
The wind direction is marked with NSWE direction.
