HTCC-AB01 - Wake Up using Switch on GPIO7 - Problem [Solved]

#1

I have a sensor that reads water level every 15 mins. There is also a trigger (float) that will be activated when water reaches a full level. This switch its attached to GPIO7 so it will wake up the AB01 when the float is raised by the water.
This means that the switch will stay Low (switch on) as long as the water level is full.
This is causing a problem in my program. It seems to be that GPIO7 is used also for resetting. Is there a way to ignore the state of GPIO7 until it goes back to HIGH ? (Switch Off).

Solution:
Use internal pull down resistor.

INPUT_PULLDOWN and wake up when RAISING.
