Product Overview

The BS412 is a smart digital pyroelectric infrared radial sensor from NANYANG SENBA OPTICAL AND ELECTRONIC CO., LTD. This compact motion detector integrates all necessary electronic circuitry within its housing, requiring only a power supply and power-switching components for a complete motion switch solution. It features digital signal processing (DSP), power adjustability for energy saving, a two-way differential high impedance sensor input with temperature compensation, and a built-in filter to screen out interference. The BS412 is insensitive to RF interference and offers a Schmidt REL output. Its applications include intelligent appliances, alarms, motion detectors, sensor lamps and switches, security systems, and automatic control.
