Octopus PIR Sensor Brick

Octopus Electronic Bricks! You can use them build electronics projects just as easy as piling bricks! By using Octopus electronic bricks, you may connect Arduino or compatible boards easily with various digital, analog and I2C/Uart interfaces. These breadboard-less firm connections includes an extensive collection of modules like potentiometers, sensors, relays, servos, and even buttons.  Just plug and play!

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, with a 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

You can see the whole program from the link.

Result

Once any movement made by human or animals within the range of 5 meters was detected by PIR sensor, micro:bit will display a rectangle; when there is no movement detected, micro:bit will display a heart.
