Design the Detection Zone First

A Sensor is reliable only when its view and target are controlled. Build the doorway, crop row, or machine path first, then place the sensor where unrelated movement cannot trigger it.

  • Test from the edges of the intended detection area.
  • Use color settings only with a consistent paint convention.
  • Combine with a Logic Gate when one detection should not be enough.
