Octopus PIR Sensor Brick
OCTOPUS PIR Sensor module is a type of electronic building block based on AM412 pyroelectric digital smart sensor. It can be used in sensing and detection of human or animal motion, sensing distance is about 4-5 meters.
Power supply 5V
Digital signal processing:< SP
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
Working temperature -25 ~ 85
Connect octopus PIR sensor brick to P0 port on OCTOPUS:BIT.
