What is the F02 command mean?

I found the F02 command is not ready, so I want to implement it by myself.
But, what is the command mean? N is the counter of pulses from flow meter?

Example : “Water Flow Sensor - 1/8” SKU: SEN0216":

1L = 5880 square waves

So I set command –
“F02 N5880” – Set 1L water flow .
“F41 P9 V1 M0” – enable the water pump.
then it will watering 1L and close the pump? right?


After careful thinking, I will define the N to water capacity (mL) for now.
“F02 N1000”


  1. Enable the water pump
  2. Watering 1000ml
  3. Close the water pump.
