I want to 2 NPN sensor connect to WEMOS board.
How can connection digrams? our trial is fail.
sensor1 effect sensor 2 :(



Product Introduction Detail:
1. Driving Port Signal Voltage:3.6-24V
2. Output Port Voltage Port:3.6-30V
3. Jumper Cap Can Achieve Output Port Is High POtential Or Pull Down Output
4. Onboard 4-Channel 817 Are Independent:can achieve different voltage control at then same time
NOTE:
The input port is shared with GND;
The output ports are independent of each other

You will get a inverse signal on then
Thank you for reply @tigrot ;
I am not technician (elktronic/automation). Therefore your comment is high level for me.:oops::oops: soryy

I showed simply it. I connected like under below. And i read code like under below. After I cheked logs....
Some time; Its wrong. 2 Port(d3 &d4) is open, but its not change !!!!

The resistor network is a little unbalanced, but should work well.
In case it doesn't work short circuit 3k resistor on V1 side.
some times read voltage
Wemos D3 for 3.35V(led off) 1.0V (led on)
Wemos D4 for 3.12V(led off) 0,8v (led on)

is it normal?

thank you for sharing
4,3Kohm resistor for all wemos pin? or only pullup pins?
