## A standard "break beam sensor" uses a laser or LED with a device on both
## sides of an opening and is triggered when something breaks the beam
## (such as a customer walking through the beam). Some garage doors use them.
## Stores often use them at the entrace to ring a chime when a customer enters
## or leaves.

## This is my attempt at using a VL53L0X i2c Time of Flight sensor 
## as a break beam sensor in Home Assistant using ESPHome.
