Passive infrared (PIR) sensors work with security systems, lighting controls, and automated doors and gates to make buildings safer. A block diagram shows components Littelfuse and its subsidiary Zilog provide for these motion and presence sensors. In addition to PIR sensor units, we offer microcontrollers, reed relays and solid state relays for alarms, and several types of overvoltage protection.
