Is there anyway to drive a small LED with this sensor without the arduino board
Thanks
I moved your topic to an appropriate forum category @betty0513.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
Yes, connect the LED with a resistor in series between the output pin and GND.

Its polite to include a link to and special parts betty - like this
Simply, the answer to your question is yes.
Now if you would like to give more detail than 16 words we may be able to be more help
Diagram show an open collector (NPN) output,
which means the LED/resistor should go between VCC (supply) and output.

You are correct, I looked at the wrong datasheet, it was not the one for the NPN model. 
Thanks guys got it
Next time I will include a link
Have a good day
Im looking for LED lights and came across these. I was always under the asumption that LED's are Polarity sensitive and wont work in reverse'
How do these work
LED Bulbs
AC LED bulbs have a bridge rectifier inside, so polarity doesn't matter.
That 80watt is more like 80mW, and take the lumen also with a grain of salt.

I did not know that. If i lowered the Hz from 60 would i eventually see the LED flicker.
Sorry i guess i did thats i guess whats in all my AC LED bulbs. So does the bridge rectifier change the AC to DC and change the polarity.
The rectifier directs the supply for the right polarity of the LED.
Larger (mains AC) LED bulbs have smoothing caps inside, to reduce mains flicker.
I doubt these small bulbs have room for caps.
