The 68HC908QT4 is the core processor of the Low-Power Optical Smoke Detector. Using an infrared LED and receivers, the unit detects the presence of smoke particles in the air, thus triggering a signal to any commercial fire-monitoring panel so that an alarm can sound or other recovery actions can be taken.
