Does anyone know of components to DIY this type of project? I like the idea and its size, mainly the laser tripwire.

  Almost certainly using a ToF (Time of Flight) sensor. They became available about 5 years ago for use as smartphone proximity sensors, but they have a range of around 1m. https://www.adafruit.com/product/3317 https://www.adafruit.com/product/3317
