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.
Specification:
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
Size:<32.00mm×24.00mm
Quick Start
Hardware Connection
Connect octopus PIR sensor brick to P0 port on OCTOPUS:BIT.
Programming
Code

Jargon buster
Plain-language definitions for the technical terms used above.
- PIR sensor
- A passive infrared sensor detects changes in heat, usually from a person moving across its view. It matters because PIR sensors are common for lights and alarms, but they can miss people who are present but not moving much.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
