Main component : AM412 - AM412 is a new digital intelligent PIR sensor. 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.
• 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
