Pulse Counter Problem
Posted: 11 May 2021, 12:42
Hello guys! I think i need your help
I have a water meter that has build-in reed switch. every 100l it will close the reed switch.
I connected the input cable from the water meter to my Wemos D1 GND Pin and the output cable goes to the Pin D6. Also i have a 4,7k resistor between 3,3v and D6.
With my multimeter i can measure the voltage. It goes from 3,3v to 0v and stays there for 2 seconds until back to 3,3V. So 2 Seconds 3,3v and than 2 seconds 0V. So sounds good. Everytime it goes to 0V, one pulse should be counted.
But its not happening. Can somebody help me?
In the Attachments ther is a photo from my settings.
Would be nice if we could solve my probelm.
Best Regards
