E-931-S35RRQ photobeam sensor

Other Hardware Sensors

Hello,

I have E-931-S35RRQ photobeam sensor and want to connect to Arduino. Could somebody explain how I should physically attached wires (what mean Brown and Blue I understand)? Which wire(s) are for Ground and which for connection to Arduino digital (?) PIN.

Thank you.

You could take the White to a digital pin and the Black to ground (or vice versa, doesn't matter), but make sure you use pinMode(pinnum, INPUT_PULLUP); so the pin's at 5V normally. Then when the relay flips the pin will go low- look for a low in your logic with a digitalRead();

Describe what it is you're trying to do: what's the Arduino role here, since it seems to me that usually that sensor controls say a driveway gate motor direct.

Thank you for quick answer. I making Start/Stop time gate and this sensor will work as beam for start. When somebody interrupt line then timer will start.
