SD4101R is an integrated PIR (Passive Infra-Red) controller IC with very low power consumption. Its internal analog and digital mixed signal design architecture results in very stable operation under various environment conditions.
SD4101R employs PIR human pyroelectric infrared detection technology. It has built-in high-precision algorithm that is adaptable to current environment, filters out ambient interference, and effectively extracts human signals. The sensing range is more than ten meters. Application circuits are simple, and do not need tuning during development or production, thus saving product space and manufacturing cost.
