ECNC-SC04 How to use proximity sensors.
Posted: Fri Sep 25, 2015 8:35 am
Hi! I just bought 15pcs of this tiny controller board. Stable output and good acceleration!
What I need to understand is how to use proximity sensors instead of micro switches. I've tried some NPN normally closed but it didn't work properly. My guess is NPN normally open but would like some input before I spend more $$$
I tried these sensors because I saw some other seller having it (random prox sensor and no info as usual) as an example on a picture on the internet..
What sensor should I look for? I need to detect metal without touchy-touchy
Best
