Domoticz

Hello,

i am using a nodemcu unit buy a wemos-d1-mini will work as well
it is running ESPeasy software
as a sensor i am using a LJ12-A3 proximity sensor which picks up magnetic disturbance
this thread will help you
i did not use a voltage converter but i used an optocoupler

i am using a nodemcu unit but a wemos d1 mini will work as well

input NodeMCU and Wemos D1 mini both have 3.3 inputs
sensoren work correctly on 5V

attach sensor to 5V but inputs through a pullup resistor to 3.3V

Thank you so much for the detailed information.

your welcome.
to be more specific, i checked and i have the sensor hooked up to D5(not D13)

it turns out the esp pulsecounter sends out a time between pulse in ms. i use this number to calculate the exact flow and send this value over to domoticz.

Just another question: does the time value sent by esp pulsecounter is specific to espeasy? I'm wondering whether I could use Tasmota instead.
