Module does't work correctly. When you cross sensor one time it generate a lot of impulses at output pin. It looks like contact bounce effect. I'm ordered three modules, and all modules have same problem. Also this modules is wery slow! After about 300 Hz it not generate impulses. As solution of this problem I use opto sensor without elecronics on this module. It wery simple schematic, but it is work wery good! See image in attachment.
