I have integrated a sensor to trigger a water pump to dispense water and sanitiser.
However, this sensor stays on for a minimum of 5 seconds after a person moves out range.
I have tweaked the time delay potentiometer to the lowest setting, and that's 5 seconds.
I want to be able to reduce it to just 1 second or TURN OFF as soon as a person moves out of range of the motion sensor, to avoid waste water.
How do I do that?
I understand that the sensor has a limitation. How can I circumvent it, or devise something around it to shut off before the default 5 second minimum delay?
This device has a BISS0001 passive IR switch that detects motion.
Look at the delay time 'minimum stating 5 secs adjustable (snapshot from the data sheet.) This is the one I want to reduce even further.

Found an interesting link on Youtube that tells to short the R13 and R33 so that the delay time gets reduced. I shorted the resistors, but still no effect.
