Usually high power

It seems to work fine, but the power is usually high, and if there is an obstacle, the output will turn off. The Arduino has an input pull-up function, but no input pull-up, so a resistor to ground had to be used to change state. Not a big deal, but I think the output would be better if it were grounded when triggered.

Pros

Pretty package

Cons

I don't remember
