Hello. Is there a way to make sure I could achieve this condition. I am using a proximity sensor, which is connected to raspberry pi. There are times when the raspberry give me input even though the proximity doesn't detect anything ( for many reason, I believe), but I realize it happen so fast when normally the proximity would take some times before it changed it state due to the passing product. I think I could "filter" this condition if there is a node, or a function that make me able to give a minimum time before it passing the data to the main function.
Thank you very much.
Edit: In case of raspberry actually I found out that you could use internal resistor ( pull up or Pull down ) on the said pi, to reduce unwanted pulse to the GPIO. However now I realize that the said product actually had a color that actually cannot be detected as obstacle ( BLACK) on the middle side , which result in triggering the pulse twice in one product. The node or function filter might be needed after all).
