PA Designer: Try It Out

Having found a threshold value that is a good balance between false positives and false negatives for your choice of bell in your noise environment, how good is your robot at sensing the bell ring from a distance?

At what distance does it become ineffective?

Experiment with ringing your bell directly in front of the sensor from different distances away to see how far you can go before the bell becomes indistinguishable from the ambient noise of your environment.
