This product series is an integrated PIR (Passive Infra-Red) controller IC with very low power consumption. It features PIR human pyroelectric infrared detection technology. It has a built-in high-precision algorithm that is adaptable to current environment, filters out ambient interference, and effectively extracts human signals. The sensing range is above ten meters. The application circuits are simple and do not need tuning during development or production, thus saving both board space and manufacturing cost.
