Guard sensor should be treated as a normal CapSense sensor. It should be tuned in such a way that it is triggered only when there is a stream of water present in the board where there are CapSense sensors. The firmware should be written bu the user in such a way that when the guard sensor is triggered ('1'), all the other sensors should be disabled (shouldn't be scanned) except guard sensor.
Is there PSoC4S sample project using guard sensor?
I do not know the recommended code processing when using guard sensor.
Should be button sensor scan itself stopped when guard sensor’s touch status becomes “1”?
Or is it OK that user only ignore all button sensors data without stopping button scan while guard sensor’s touch status becomes “1”?
And how should user handle button sensor when guard sensor’s touch status returns to “0” from “1”?
Should baseline initialize once before starting button scan when guard sensor’s touch status returns to “0”? etc.
Please provide recommended scan method, scan flow and sample project etc, when using guard sensor.
