Question on optical sensors

kelleymc · Feb 11, 2023

How long does an optical sensor need to be submerged to trigger a closed state? Is there a way to extend the time before the alarm is triggered?

In other words, if it triggers immediately when submerged, could I code the alarm to trigger once it’s been submerged for 5 seconds?

They change state as soon as they detect a fluid.

It's up to software to delay any action.
How you would do that depends on which controller system you are using

If you are using apex then it is immediately. Use defer statement to state how long the sensor needs to be activated Before turning on/off

If Sense1 = Closed Then On
Defer 0:00:05 Then On

5 seconds before it will activate

Using Apex Fusion

Thanks. I’m trying to slow down how often the alarm triggers on one sensor, not turn anything on or off. Sometimes water movement trips one sensor so I want it to be submerged for a certain period of time before notifying me.
