Your little robot keeps ploughing into the coffee machine. This sensor sees what's in front of it and tells your controller to stop. Runs straight off either the 5V or 3.3V rail on your board – no extra supply, no wiring headache. Two potentiometers let you dial in the detection frequency and beam intensity, so it works under a bright shop light or in a dim garage. Four-pin header. Plug it in, calibrate, and your build starts making sense
