#36986 Just wanted to share a hardware mod I did on a motion sensor I picked up at Harbor Freight for $12

In short I was able to add a $10 NodeMCU 1.0 to a wireless motion sensor and have it email me when there was activity.

The normal price of this motion sensor is $29, and with the discount I got, I was able to add this mod and have it cheaper than the orginal price.
