Reading open collector output (UVTRON driver board)

Using Arduino Sensors
1

Hello, how might I read the output from this driver board? Im using a esp8266.

Thank you !

Connect the module output pin to any pin (can use for input) of ESP8266 as it is, and set pinMode to INPUT_PULLUP.
That's all.

Don't forget to connect the module GND to the ESP8266 GND.

It seems that the timing is the same output 1 and 2 except that the logic is inverted.
