SENSOR MANUAL
Pyroelectric Infrared Radial Sensor
TYPE: BS412
NANYANG SENBA OPTICAL AND ELECTRONIC CO.，LTD.
Digital Smart Pyroelectric Detector BS412
BS412 is a newest smart digital motion detector with a small window size. It
offers a complete motion detector solution, with all electronic circuitry
built into the detector housing. Only a power supply and power-switching
components need to be added to make the entire motion switch.
BS412 includes the time setting only.
Features and Benefits
- Digital signal processing（DSP）
- Power adjustable, save more energy
- Two-way differential high impedance sensor input and temperature compensation
- Built-in filter, screen the interference by other frequency
- Excellent power supply rejection, Insensitive to RF interference
- Schmidt REL output
Application
- Intelligent appliance
- Alarms
- Motion detector
- Sensor lamp, Sensor switch
- Security system
- Automatic control etc.
