Adding a Second Motion Sensor to an Existing LED Light Setup

So I have and LED light strip installed and setup with this motion sensor:

https://www.amazon.com/gp/product/B00K4UPPM4/?tag=atomicindus08-20

What I would like to do is add an additional motion sensor to this setup so that the lights can be triggered from either sensor.
But I'm not sure if this particular sensor will work that way.

It has an "in" for the power and an "out" going to the lights.

So I don't know how I would add a second one that works in conjunction with this one.

Has anyone done something like this before?

You could have the line coming in 'split' into two parts, one going to each sensor then they eventually connect back together on the 'out' side and just continue on to the main light so when one is tripped.

Make sure the sensor is receiving the correct voltage. Unless you have a transformer in your setup (assuming your light isn't run on 12v) then I would use a 120v sensor (assuming your light is 120v)

Those are 12-30v so you'd need a stepdown transformer and a stepup transformer. Make sure not too many amps are being drawn. But it'll work.

edit: It'd be much simpler to use a 120v one like this.
