An entrance/exit pair of Raspberry Pis, each combining YOLO detection with an HC-SR04 ultrasonic sensor. The count only changes when both fire, which removes the false positives that make cheap counters useless. The Pis synchronise, serve a live dashboard and a REST API, and can signal barriers over GPIO.

What it does

  • Dual-trigger logic: detection AND proximity within 30 cm
  • Entrance/exit synchronisation
  • Live dashboard and REST API
  • pytest suite

A camera alone counts the cat and the plastic bag; an ultrasonic sensor alone counts the trolley. Requiring both to agree is the whole product.
