智能建筑与家居应用指南
了解Littelfuse技术,帮助您增强楼宇和家居自动化应用的电路保护、电源控制和传感精度。
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.
