Hi everyone.Firstly i want to apologize for my bad english.
May i know whether i can use this sensor without its controller?

For example i want to use this sensor to trigger on a LED. This sensor comes with 2 wires.
In controller i found that this 2 wires will be connected to GND. I'm confusing about it.
Any helper pls? Thanks.marcus
You can get a controller for these for a few bucks more that will be much more useful than just the sensors.
