The YL-105 is an IR tracking and obstacle avoidance sensor. It combines an infrared emitter and a phototransistor receiver on a small PCB with onboard comparator circuitry. if (sensorState == LOW) // Object or white

Connect DO to a microcontroller input. Set the threshold so the output is LOW only when a magnet is within 5mm. Mount the magnet on a door and the sensor on the frame. When the door opens, the magnet moves away, and the output goes HIGH, triggering an alarm. Connect DO to a microcontroller input
