Pir-Am612

Digital Smart Pyroelectric Detector AM612

AM612 is a newest smart digital motion detector. This Smart digital detector 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, a timer is included. The series has versions which can include ambient light level and sensitivity adjustments.

Features and Benefits
  • Digital signal processing(DSP)
  • Power adjustable, save more energy
  • Two-way differential high impedance sensor input
  • Built-in filter, screen the interference by other frequency
  • Excellent power supply rejection, Insensitive to RF interference
  • Schmidt REL output
  • Low voltage, low power consumption, instantaneous settling after power up
Applications
  • Toys
  • Digital photo frame
  • TV, Refrigerator, Air-conditioner
  • USB Alarms
  • PIR motion detection
  • Intruder detection
  • Occupancy detection
  • Motion sensor lights
  • Computer monitor
  • Security system
  • Automatic control
  • Corridor
  • Stairs Lights etc.
